Quick Tips 001: Color Swatch Keyring

I have this really rad poster of all of the current Procion fiber reactive dye colors, and it has been really helpful in making color choices for my projects, but it's not exactly easy to see what colors complement each other. In the following example, I'll show you how I solved this problem by turning my poster into a set of swatches.

First, I suggest that whatever poster you're using, you buy two of them. One of the posters you will keep intact, and the other you can make into swatches. Sometimes it's nice to have your colors still displayed as a poster.

At Dharma's they have these two posters available:

Fiber Reactive Dyes
Acid Dyes

Depending on your craft, whether you use glazes, paints, or dyes, often times you can even find free brochures that have color swatches printed on them.

The first thing I do to my poster is have it laminated to enhance the durability of the swatches. If you don't have access to a laminator or it's too expensive to have done, I have some other tips for you which you can do later.

I then draw lines across the poster in between the swatches. I measure carefully to make sure the lines are evenly spaces so that my swatches will be the same size.

For my project, my swatches were 1 3/8" tall and 1 5/8" wide.

 Next I cut the poster into long strips following the lines I drew.

 I finally cut the strips into individual swatches.

 *I you haven't laminated your poster yet, now might be the time to do it. You might be able to fit trimmed-down strips or individual swatches into a smaller laminator. The benefit is that all sides of your swatches will be sealed, making them a little more water proof. The drawback is that you have to cut them out again! If you're looking for a cheap hack, use packing tape. Unroll a length of packing tape sticky-side up, and place your swatches on the tape. Unroll another length of tape and carefully apply to the other side of your swatches. Now you can cut them up again!*

 To keep all the swatches organized, I decided I wanted to keep them on a keyring. I punched a hole in the corner, not less that 1/4" from the edge.

I used the first swatch as a template for marking the location of the holes on the remaining swatches so that they would sit evenly on the keyring.

 After all the punching, I discovered a secret. The hole makes a nice window to see how colors look together! 

Don't attempt to secure your swatches with a traditional spiral keyring; you'll damage the holes! Either use a threaded key ring, a hinged key ring, or a small decorative carabiner like I did.

 Now you have all of your swatches protected, organized, and ready to play with!

Pintering 001: My Most Popular Pin is Garbage

So far, very few of my pins get re-pinned and that's fine because my boards are for my amusement primarily, and if others enjoy my curations, well, that's pretty rad too. It ends up being a pretty big deal when I get a re-pin as notifications get sent through multiple apps via every device I have. The notifications have been pretty frequent the last few days, but I've been too busy to follow up. I finally did. Here it is:

Some time ago I wrote at length about my disapproval of toilet paper tube art. In doing so I ended up pinning an awful lot of crap I do not even like. What I didn't think about is that people would see my pins and then also pin them. Somehow I doubt these re-pinners are as cynical as I am, and were probably re-pinning because they were actually inspired by this thing.

I know beauty is in the eye of the beholder. I try really hard to embrace this concept, but really, look at this thing. The painting is sloppily done, it's obvious that it's made of toilet paper tubes, the color palette is uninspiring, the composition is dull, and there are some cheap looking little plastic pearls glued to the flowers unnecessarily. As far as all toilet paper tube art goes, it's one of the least skillfully done projects I've ever seen. It's displeasing to look at. It's just bad. But that's just my opinion. (If I'm being honest, it's not just my opinion. This thing is objectively, not subjectively, bad.)

Yet it has the most re-pins of all of my pins combined.

I get notified every time it's re-pinned and I get to see who's re-pinned it. I click on these people to look at what they pin and sometimes I'm treated to the worst taste ever, and sometimes I find a person who seems to have pretty good taste, and perhaps just had a momentary lapse in judgement. Or maybe they're just assholes like me who enjoy ironic pinning.

It's an interesting window into what people value, and it leaves me feeling lonely sometimes. I've got these pins of people from all over the world doing their craft, and they get very few pins. Maybe it's just the luck of the Pinterest algorithms and not just that people love painted garbage more than the cultural heritage of craft.

Science of Craft: 003 The Structure of Cotton Fiber


Surely you've heard the fairytale of Rumpelstiltskin. Some chick finds herself in a predicament that requires her to turn hay into gold thread otherwise she'll be executed. Luckily some woodland spirit named Rumpelstiltskin comes to her aid in exchange for the distressed damsel's first born. Things turn out pretty much how one might expect. Now, if you know about bast fibers, you might be heckling our heroine from the sidelines. Congrats, you are the real life Rumpelstiltskin. Certainly, you're not going to be making anything out of hay, but our girl is probably mistaking flax for hay. But she's not the only idiot. The king who wanted her to make gold thread was only ever going to get linen, which is a wonderful material in its own right. Too bad they didn't have Pinterest back then, where they could have learned to class anything up with a spritz of metallic Krylon. Anyway, I grew up enjoying Shelly Duvall's Fairytale Theater, and looking back on this scene (10:54), it's especially hilarious to me now. What a good show.



Now, try suspending judgement on our poor heroine for a moment and try empathizing with her incredulity about spinning plant fiber. It does seem pretty weird, but it's amazingly doable as long as you can find a way to get at the cellulose that makes up every plant. In case you forgot, here's what I'm talking about.

One cellulose unit


This is a unit of cellulose, which has such wonderful properties which human beings have found many uses for. It's part of what makes up the fiber in our diet, it's what makes up the lumber we use, the pulp in our paper, and the plant fibers that we spin. However, there are a couple of factors, polymerization and crystallinity, that make any given source of cellulose better suited for one application or another.

Polymerization

Take a look at that cellulose unit again and notice the oxygens (in red) seemingly just hanging off the ends. That's where the cellulose units attach to each other. These attachments are particularly strong bonds known as covalent bonds. That's when a couple of atoms actually share electrons with each other. For cellulose in particular, the connection between the sugar subunits is called a glycosidic bond, and they always occur on the first and fourth carbons, connecting unit to unit, to another unit, and another, and so on, which makes a polymer. Polymers are molecules made of long chains of smaller units repeated together. A good analogy for polymers would be pop-beads. The beads would represent individual atoms and the "pop" part would be the shared electrons.

The longer the polymer, the better it is for whatever you're doing with it. When making paper, using long cellulose fibers makes a sturdier, more flexible paper. You've experienced this if you've ever noticed the difference between drying your hands on recycled paper towels and using some premium brand like Brawny or Cottonelle. Whenever we recycle paper, those polymer chains get damaged and broken, thereby shortening them. I once had a student insist on using the crummy brown paper towels to make recycled handmade paper. Besides the fact the she wasn't really recycling anything by unwinding the roll of fresh unused paper towels, the paper came out extremely weak and friable, just like I told her it would. There's only so many times you can recycle cellulose fibers until they are too short to do anything with.

It may not be surprising that paper makers often add cotton to their paper pulp to enhance the quality of their paper. I know my interviewers must have been impressed with the cotton stock I printed my resume on. Anyhow, I'm saving the short fibers left over from my cotton spinning and will see if they help a all with my paper making. Of course, the longest fibers are more desirable for spinning, but cotton is notoriously short (usually no more than an inch) compared to animal fibers which intimidates a lot of people, but obviously it's got a long enough staple length because people have been spinning it a very long time. One just needs to use different techniques and make a few adjustments to existing equipment to spin cotton, and someday I will go on at length about it.

Crystallinity

I hope you haven't been equating a single cellulose polymer with a single cellulose fiber. Cellulose fibers are actually a much more complex arrangement of many polymers bonded together more or less in parallel. The more parallel and tightly packed the polymers are, the higher the degree of crystallinity is. This makes cotton pretty strong, especially when wet, a feature animal fibers can't claim.

The hydroxyl groups that are key in dyeing of the fiber, as we have learned, but they are also what gives cotton its high degree of crystallinity, because they are so very attracted to each other. This is due to something called polarity which creates the condition for hydrogen bonds to form. This won't be difficult to understand if you can stick with me. Ha. You know how opposites attract? That's all that's really going on here, and in this case the opposites are negative and positive charges. The oxygen has a slight negative charge and the hydrogen has a slight positive charge.
This unbalance didn't just happen for no reason. Oxygen is a greedy asshole, and in bonding covalently with hydrogen, doesn't share the electron quite fairly. It's like if you were to split lawn mower ownership with your neighbor, and yet it spends more time in your neighbor's garage than yours. The lawnmower represents the electron in this analogy, keep up with me here. Anyhow, electrons have a negative charge, and because oxygen is bogarting the electrons, the oxygen ends up being more negative and the hydrogen ends up being more positive.

If the hydroxyl group from a cellulose polymer encounters a hydroxyl from another molecule, the positive hydrogen is going to be attracted to the negative oxygen of the other hydroxyl group. This attraction forms the hydrogen bond. It's not as strong as a covalent bond, but considering how many potential hydrogen bonds could be formed all up and down a cellulose fiber, overall, that's going to make a pretty tough fiber. The more hydrogen bonds form with adjacent cellulose fibers, the more closely organized in parallel the polymers become. This is crystallinity.

A hydrogen bond between the hydrogen in a
hydroxyl unit and the oxygen in water.
You know what else has Hs and Os bonded in it? Oh come on, do I have to spell it out for you? H two Ohhhhhhhh, now you get it don't you? Now remember, oxygen is an asshole, even in water. It has a slightly negative charge and water's hydrogens have a slightly positive charge. When water meets a cellulose fiber, the water becomes attracted to the hydroxyl groups in the cellulose. That's why I have 100% cotton bath towels. Nothing dries your butt crack better.

Fiber Structure

If you've got good eyes, it's pretty easy to tease out a single cotton fiber and look at it. That is not one polymer chain. It's not even a bunch of polymer chains hydrogen bonded together. One cotton fiber is actually many layers of crystalline cellulose chains arranged in different ways, and this is what makes cotton so splendid and easy to work with. Some of the layers are twisted, which makes the fiber strong. The fiber structure of cotton is pretty consistent, having a diameter of about 12-20 micrometers. The result is a fiber that is smooth, soft, and not irritating like wool is. Fine Merino is comparable.

Cotton is so great. It comes right off the plant this way. You can't just start spinning trees you know, even though they contain a lot of cellulose. In order to "spin trees" you have to remove all of the lignins and other compounds to get at the cellulose, and by that time you just have a bunch of unspinnable pulp left over, so then you'll have to chemically polymerize the pulp, which will never be as long or strong as cotton polymers. What I just described there is how rayon is made. Through some physical effort, bamboo, and bast fibers like linen and hemp, can be processed into spinnable fibers. Cotton, though, is a clear winner for me.


If you want to know more, here are a couple of more technical pages on the structure of cotton. Have at it!

Bullshit Crafting Product: 002 Toilet Paper Tubes

I was inspired to see if my cotton seeds were still viable, so I put one in a sawed-off water bottle filled with soil to see what would happen. After watering, it sprouted in a matter of days. Truly a miracle since these seeds may very well be 5 years old or older. I can't remember the last time I went picking cotton bolls in my father's garden. When the sprout grew large enough to transplant, removing it from the bottle was very difficult. I had to slice the bottle down both sides to get it out and I'm pretty sure I damaged some of the delicate roots. By this time I had tried sprouting a few more seeds in the same way, and they did not survive the transplant when it came their turn, though I suspect one fell prey the the moth grub problem my patio has.
I would not have even bothered using the plastic bottles, but I have a shitton of them already prepared left over from a student experiment with plants. At the end of the experiments, I eventually had to get to work cleaning out the plastic bottles so I could recycle them. During the grueling work I had ample opportunity to reflect on whether or not repurposed bottles were the way to go. Would my students have used as many water and soda bottles in the first place if I hadn't told them they needed to bring some for an assignment? Was there really any environmental benefit to using the bottle as a pot before recycling it? We already had to rinse them once to use as pots, and then rinse them again so we could toss them in the recycle bin. What a waste of water! There has to be a better way, and I think I found one on Pinterest. What a great idea, using toilet paper tubes as seed starters. You can transplant your seedlings without un-potting them and the paper tube will decompose easily in time. Furthermore, I've always been a little dubious when I toss tp tubes in the recycle bin. These things aren't made out of the greatest paper pulp quality, and I can't imagine they recycle into anything very well anyway.
I did a little bit of research to see how other people were starting seeds. Thanks to the nosy nature of Google (second only to my grandmother) I started getting eBay ads for rolls of toilet paper. It's a thing friends, and I'm not even the only one who has noticed. Now why in the world would someone be willing to pay for and ship bulk toilet paper tubes? In my heart I hoped it's because everyone is really getting into gardening and need tubes for a massive amount of seed starting. Pinterest, well aware that I was showing interest in toilet paper tubes, showed me far more impractical applications that really pushed the boundaries of taste.

Adults are seriously making home decor out of toilet paper tubes. Mostly, the end products really, most definitely, look like they were made out of toilet paper tubes. Like, if someone invited me to their house, showed me their toilet paper tube wall art, and asked me to guess what it was made out of, I would instantly say toilet paper tubes. One of the problems in disguising this art form is that the most common design element is the simple squashed-tube shape which makes
a leaf-like design. It really, really just looks like a squashed toilet paper tube.


One way to disguise the material is to paint it. The problem with toilet paper tubes is that the crummy pulp the tube is made of is pretty absorptive and it's fuzzy, paper-pulpy nature often shows through. Even if it's painted with many layers or given a good dose of spray paint, it still looks like a painted toilet paper tube. Glitter seems to help, but I'm not an advocate of glitter-based solutions.

Some toilet paper tube art uses paper quilling techniques to add diversity to the shapes and patterns your art can take. However, the cardboard that is used to make toilet paper tubes isn't very forgiving. It's really crappy quality, and should be. It's a toilet paper tube. If you try to fold, bend, or roll this material, it tears, crumples, and frays easily. I'm not just imagining this either. I got roped into making party favors once with these things, and it's not easy. Considering what a frustrating craft material toilet paper tubes are, and their terrible quality, I don't know why anyone would put so much effort into something that is going to fall apart.

People with far more patience and skill than I have done some truly impressive things with toilet paper tubes, but you probably aren't one of those people, let's face it. I can see a theater set designer pulling off some impressive faux wrought iron using toilet paper tubes, and to me, the stage seems to be where this skill belongs. Up close, it's obviously toilet paper tubes.
Most likely will not be
used for actual canning
There are enough bottle caps in landfills,
Why do we need pre-decorated ones?
At the very least, craft stores haven't found out about this trend yet and started selling better quality vintage paper rolls like they do with those Ball jars and bottle caps of all things. So, while I have a lot to complain about, these toilet paper tube creations are actually repurposing trash.

The Process: 002 Dyeing Cotton Lint (Cold-Hearted Batch)

I was disappointed with the results from both tub-dyeing and direct application, so I tried something similar to the method I used when I brushed fiber reactive dye directly onto fabric, only leaving out a thickener since I won't be applying the dye as one would apply paint. I was pretty happy with my results from my painting, but unfortunately I don't have any photos. The process involves making a batch of chemical water, which includes urea and sodium alginate. The urea helps dissolve the dye, thereby increasing your yield, and it also keeps it wet, which is necessary for the reaction between the fiber and the dye. The alginate is the thickener, so I left that out. The sketchy part is once you add the dye to the chemical water, you also add the soda ash. This means you need to use the dye within the hour. While soda ash raises the pH, which makes it easier for dye particles to react with the fiber, soda ash also reacts with the dye itself, making it inert. That made painting very nerve wracking. There's no fussing about and no carrying on a painting for longer than an evening. However, I'll be applying the dye to my cotton almost immediately so hopefully the time limit won't matter. Since I had such good results with my painting, I'm feeling a little more optimistic here.

The reason I'm changing the way I'm doing this is because in my previous trials, the cotton was still saturated with liquid by the time I applied the dye, which I suspect caused the pale colors. I'm also unhappy with the state of the cotton after the process was over. Though I was careful, a lot of the cotton is moderately ropey now. It's not unusable, but will definitely be a pain to process into something spinnable. Also, during the process, the clumps of cotton developed air bubbles which may have also affected the availability of the fibers to the dye.

3 ounces of roughly combed cotton
To address these issues, I combed my cotton into foot-long roving like logs. You would probably card them into loose rolags. Nobody I know of hand-combs cotton. Just me, because that's what I have. Combs. Anyway, my idea was that in organizing the fibers ahead of time the cotton will be easier to handle during and after the dying process, and hopefully will make the fibers more available to the dye.

It was a huge pain in the ass, and I kept having to remind myself to do a shitty job since I wasn't going to be spinning yet. I just needed enough effort to roughly organize the fibers. Look at all of that, and it's only 3 ounces! I've got about a pound more to do in the future.

Washed cotton logs drying in the sun
Wearing exam gloves, I washed each log individually with PTD, and then rinsed them in a wire strainer. Then I let the suckers dry. Actually, I ran the hair dryer on them for awhile, but damn it, I had already spent enough time with these guys, so eventually I just crossed my fingers that they wouldn't blow away or get stolen for nesting material, and put them outside in the sun. I took a bike ride to the cafe and had some espresso. That was more fun than running the hairdryer.

Once the cotton was completely dry again, I was ready to dye. My idea was to use the recommended amount of dye per volume of water for one batch, and then increase the proportion of dye in two more batches. I planned to do this for two different colors, 22 Cobalt Blue, which requires twice the amount of dye as most of the dyes, and 50 Jade Green, which requires the standard amount of dye, but because it has a tiny amount of copper in it, it does better when exposed to heat. What's this now? What happened to Deep Orange? Honestly, I do not need any more orange fluff. Changing colors certainly makes this experiment harder to compare to previous methods, but as long as the outcome is intense, as opposed to pastel, I will be happy. Anyway the following table is the result of a lot of math:



Cobalt Blue
Jade Green
Recommended Amount of Dye
2 tsp dye per ½ cup of water
1:12 ratio
1 tsp dye per ½ cup of water
1:24 ratio
Recommended + ½
3 tsp dye per ½ cup of water
1:8 ratio
1 ½  tsp dye per ½ cup of water
1:16 ratio
2x Recommended
4 tsp dye per ½ cup of water
1:6 ratio
2 tsp dye per ½ cup of water
1:12 ratio



The dye powder measured into scrap paper weigh-boats ahead of time
(Protective mask, eyewear and gloves used of course)
I mixed 3 tablespoons of urea into 3 cups of warmed distilled water to make my chemical water. I used a little bit of this water to paste-up my dye. In a separate cup I poured in nearly a half cup of the chemical water and dissolved a half teaspoon of soda ash into that before pouring it into the dye paste-up. I'd add more chemical water if I didn't quite make it to a whole half cup.
Pasting-up in progress
Golly, for some reason, I thought it would be a good idea to lay out my cotton on plastic wrap and squirt the dye onto it from there. It was not a good idea. My execution left a lot to be desired. First of all, I was shocked when the dye just beaded on the surface of the cotton and then rolled off. Then I was horrified when the dye started to puddle and flow towards the end of the plastic wrap. Look at this stuff. Do you want that spilling onto your countertops and dripping onto the floor? If I made my coffee that black I'd be up for days. Anyway, I resorted to massaging the logs of cotton to encourage them to absorb the dye, which they eventually did. You know, cotton fibers are actually made of layers of cellulose arranged in a particular fashion, with a final waxy coating. I was under the impression that the wax was removed during the process of scouring and washing. So imagine the pit in my stomach upon the realization that the wax was obviously still there, repelling the water. Would it even take the dye? Well, it was too late to turn back now. So I massaged away and then awkwardly wrapped everything up in the plastic wrap.  Time for Plan B.
Ha ha ha look at this slippery blue turd ensconced in plastic wrap. Such a terribad idea
Moving forward, I decided to use sealable bags instead. I put about a half ounce of cotton in each bag. I would then mix up my dye as before, then pour it directly into the bag with the cotton. I sealed the bag and massaged the heck out of that cotton. Once I was satisfied the the dye had been throughly absorbed, I squeezed out as much air as possible and made the final seal.
Eventually, the cotton accepts the dye and the volume decreases.

Rinsing
Meanwhile, I warmed up a pot of water on the stove. I took the pot off the heat and put the bags of Jade Green cotton in the hot water bath. The Cobalt Blue bags were unceremoniously dumped in a plastic basin. My plan was to leave all of this stuff outside for 24 hours, but I got a little, um, distracted by someone special and I didn't get to rinsing until 10 hours later than what I had planned. I took the cotton out of the bag and rinsed and rinsed and rinsed and, oh my gawd, blue dye is still coming out and the cotton is still BLACK. You can see the rinse water in the photo. Every bag was like this. My conclusion is that I really went overkill on the dye and don't need that much at all. Also check out the holidays. I need to work on my masseuse skills. Once I was satisfied with the clarity of the rinse water (in all honesty I was just bored waiting) I put it all in plastic basins outside, filled them with water from the hose and let it sit overnight. The next morning the soak water was freakin' dark with excess dye. After one more rinse and a squeeze, look at what I've got.

Conclusions and Results

Cobalt Blue post-soak



Jade Green post-soak
Well, that's certainly more intense than my previous results.  You'll notice there are holidays where the dye didn't penetrate despite my massaging. I did a little combing and compared the different dye batches, avoiding the holidays. I'll still use the undyed fiber, but I really want to focus on the color of the fibers that did get exposed to the dye.
From right to left: Cobalt Blue at 1:6, 1:8, and 1:12 dye to water ratio and Jade Green at 1:12, 1:16, and 1:24 dye to water ratio. The leftmost log for each color represents the recommended ratio.
That's nice and all, but is this what these colors are supposed to look like? Not really. The color came out way darker than the color swatch indicated. Swatch 22 to the left there is for Cobalt Blue, and as you can see, the fibers, even at the very tip of my combed log, are way darker than the swatch. Though my camera is crap at showing it, I'm much closer to 130 Strong Navy. Swatch 50 indicates Jade Green, but the actual fibers are much closer to 153 Mermaid's Dream and 146 Kingfisher Blue.

So freakin' what you say, but here's my objection. If I wanted those colors, I would have just used those dyes. When I did the final rinse, there was way too much dye going down the drain. What a waste of both dye and water. Because of my fuzzy navel experience I went overkill. Don't get me wrong though, I appreciate the level of color saturation for sure, and I'm much encouraged. So, moving forward, here's my plans for next time:

  • Combing the cotton ahead of time was a great idea, though tedious. The fiber didn't tangle during the dyeing process, and after all was said and done, it wasn't that difficult to re-comb it. Next time though, I will make the logs smaller (say, less than a foot long) and less thick (less than three layers of combed cotton) in order to reduce the amount of holidays during dyeing.
  • In no way did I need as much dye as I used. It produced unexpected results and way too much wasted water and excess dye that gets washed out. Next time I will try another experiment, probably with the Jade Green again, because it's such a lovely color. I will try three more batches 3/4 tsp, 1/2 tsp, and 3/8 tsp of dye per 1/2 cup of water. (1:32, 1:48, 1:64 water to dye ratio.) It should be interesting to see which one of those hits the target color.
  • I'm debating whether or not I really need to wash with PTD ahead of time or not.
  • A 1:1 ratio of cups of water to ounces of fiber seemed to work well, despite the holidays in this round. With enough massaging, and making thinner logs of fiber, I think there's plenty of fluid to saturate the fibers.
  • It seems to me adding the soda ash to the dye rather than pre-soaking the fiber in a soda ash solution was key in producing the saturation seen in my samples. It's really the only meaningful difference between this experiment and the tie dye-like direct application method I used. That time I let the fibers sit for over 24 hours as well. While I'm sure letting it sit and develop os important, I think what's more important is to not have fiber that is already wet, thereby diluting the dye.
  • Since I'm not trying to paint the fibers a rainbow of colors at once, there is no reason to use plastic wrap. I plan to keep using sturdy resealable bags. They can be rinses and used multiple times, and they really help me keep everything neat and organized.
Anyhow, I won't be getting to this next experiment any time soon as I have other projects that I need to finish, but I will share my results when I get to it.

Bullshit Crafting Product: 001 Decorative Cotton Bolls

Oh what serendipity. I'm in the middle of processing, dyeing, and spinning the cotton that my father and I have grown ourselves. I've also been researching this wonderful fiber to better understand how to do all of these things to it. Then I run into these things, real cotton bolls tied to a wreath or tied to floral wire in a spray. You would think I would be excited about seeing these things, like, "Oh hey, here's a thing I'm totally into right now, made into home decor! I should decorate my house in cotton bolls and then everyone will call me "The Cotton Gal', and I'll be all about that cotton all the time. Oh that wacky LuRo and her cotton!"

Certainly a Good Use of Materials

Lately I have been posting away about my dye experiments with cotton lint, but I'm up to other things as well you know. I made the mistake of liking penguins as a child and people still keep giving me penguin things. I'm not about to start another "thing" ever again. Anyway, being into other things, I reluctantly made a trip to the nearest craft store because there was a thing I needed.

To get to the thing I needed, I had to walk through the now requisite bins and shelves of things that are not crafts. The cotton wreaths and sprays were one of the many non-craft things that were there. Oh sure, you could incorporate those sprays into a floral arrangement, or you could embellish the wreath with other bullshit, but we're cutting really close to Sandra Lee Semi-Homemade territory, and at least she has the excuse of needing to feed herself and her family. No one needs to glue shit to a wreath under such duress that you have to buy a pre-made wreath much like how Sandra Lee makes cake out of pre-made cake.

So instead of moving on with my errand and ignoring the garbage, I stuck around to inspect it because I'm an asshole and love being mad about inconsequential things. The wreath already had a dead mosquito embedded in the fibers. Lovely. Now imagine this thing hanging on your front door or in your house for a season, getting covered in dust and accumulating spiders. How the hell are you going to clean it? Smacking the dust out or vacuuming up the cobwebs would destroy it.

Don't even ask me if I touched it because of course I touched it. It's made of real cotton bolls, and yeah, I kinda pulled the fibers out a little. It's not the greatest cotton. The staple length is pretty short but it is very white. At the price of $29.99, it's certainly not cost effective to rescue the cotton in the wreaths to spin them. The tag also says its made in China, but who knows where the cotton was actually grown, but it was grown somewhere, and in that place the soil was tilled and watered and cotton was planted. It was harvested and instead of being used for making fabric, cotton balls, or topping of the tips of ear swabs, these bolls got sent to some factory where they got tied up to a wreath or twigs of floral wire so that you can display it in your house for a limited amount of time before it gets dirty and ends up in a landfill. It was pretty crappy cotton, so maybe it was going to get tossed anyway, but considering how white and attractive the bolls are, I think not. There's a chance this crap was grown specifically for this application. What a waste.

Anyway let's wrap this up:

The Process: 001 Dyeing Cotton Lint (Deep Orange? More Like a Fuzzy Navel)


I'm really jealous of the Wool People. There's so many fun fibers and colors of fibers for them to play with, but I have my insane reasons for limiting myself to cotton. In the meantime, I'm diligently spinning an entire pound of white cotton sliver, and surprise, it's not that exciting. I have plans to dye it after it's plied, but that's a long ways off. So, I got to thinking, if the Wool People are able to dye their Superwash Merino before spinning, well, could I do the same with cotton? Joan Ruane, the cotton guru, has done it before, and so maybe I can too. Then I'll have a ton (well, just under 2 lbs) of pretty fibers running through my fingers as I spin my favorite fiber ever.

Dyeing cotton is not a new experience for me. I've done a lot of shirts, sheets, and fabric. I've tie-dyed, tub dyed and painted with dye. I've taught other people to do it. I've overseen classes on dyeing. I'm not that good at it, but I understand, or at least have heard of, most of the basic ways you can add color to cotton. However, other than on the internet (and even that information is scarce), I have yet to see anyone dye cotton lint. There might be a reason not to. I'm going to find out. I tried two different methods. Tub dyeing and direct application.

Tub Dyeing

I tried to kinda-sorta followed Joan's directions and Dharma's. The following is an account of what really happened. I do not blame you for skimming past right to the results.
Oh no, it doesn't fit!
    1. I started up the computer and kick-ass sound system, then navigated to Pandora.com to put on Bjork.
    2. While the cotton lint is probably up to 99% cellulose, there might be other weird crap on there that will prevent the cellulose from accepting the dye, like natural pectins, or oils from my greasy taco fingers. So, I scoured 1.50 oz. of raw cotton with 3/4 teaspoon of Professional Textile Detergent in 1/2 gallon of water in a cooking pot that I no longer use for cooking.
    3. With gloves on, because this detergent is brutal, I submerged 1.50 oz. cotton  into the pot and squished it a little until saturated with water. At first it seemed like, holy shit, way too much cotton! With a few squeezes, I made it fit easily, with some room even. 
      Never mind
       
    4. I turned on the burner and let simmer for about 15 minutes. The reviews on this detergent complain about fumes, so I was a little worried about doing this, but I didn't get any fumes. Or maybe I gave myself brain damage such that I can't smell anymore. Who knows. I pulled the cotton up and flipped it over with spatula, then smashed it a little with spatula, all the while trying not to pull too much on the cotton, which would end up making unusable rope.
    5. I decanted the water down the drain. It was really gross and brown, which lets me know that I wasn't just wasting my time. After letting it cool a bit I rinsed the cotton multiple times in a wire colander.
      Everything's pre-measured and ready to go
    6. As far as the dyeing process goes, I weighed out all of the dry ingredients ahead of time, while wearing gloves, eye protection, and a dust mask. Most messes come from being rushed, ill prepared, and disorganized. If you weigh out your stuff ahead of time, all you have to do is add your ingredients when you're ready.
    7. I microwaved a cup of water for a minute and a half and dissolved 3 tsp of urea into it.
    8. I microwaved a little more water, added 0.03 oz of dye to it, and made a paste out of it.
    9. I added the urea-water to the dye to make a slurry. If I'm being completely honest, I actually did all of this while waiting for the pre-wash earlier.

    10. When ready, I poured a half-gallon of water into a pot and dissolved 1/2 cup of salt into pot. The salt is supposed to bring the dye to the cotton fibers. It does not fix the dye to the fiber as some mistakenly believe. Think of it this way; you have this dilute concentration of dye. It's going to need some help locating the fiber. Salt is the match-maker.
    11. I warmed up the water on the stove. I'm doing all of this heating because it will help move the particles around, dissolve them in the water, and encourage chemistry to happen.
    12. Being careful not to splash, I added the dye slurry to the pot of water.
      Half the fun is not having to clean up a big mess
    13. In went the cotton. I pushed down on floating clumps and 
      agitated occasionally. I kept a plastic cup nearby as a spatula rest in order to prevent messes.
    14. As the cotton was just sitting there in the dye bath, I dissolved 2 3/4 tsp of soda ash in warm water.
    15. After about 10 minutes, I pushed the cotton aside and added 1/2 of the soda ash-water to the dye bath.
    16. Another 10 minutes passed by before adding the rest. I pulled some fibers out intermittently, and noticed more of a golden color rather than deep orange, but 10 minutes later it seemed to be getting deeper!
      Looks promising!
    17. I stirred frequently for a half hour, trying to get those dye particles to meet the fiber, which would hopefully pop off the hydrogen from the hydroxyl groups in the basic environment. Yeah baby, drop those hydrogens.
    18. I dumped the dye bath, and then rinsed with cool water. When cool, I smooshed the cotton into a ball and gave it a good squeeze, then continued to rinse until the water was pretty clear.
    19. The pre-wash instructions were repeated.
    20. There was a final rinse and then I let it dry.


    Direct Application Method

    I'll discuss my results later, but *spoiler* I did not like my results. So I tried more of a tie-dye technique. My hope was that in introducing the dye to the fibers directly, I would get a more intense color. Anyway, I won't repeat the pre-wash directions because the are the same. By the way, I substituted Kate Bush for Bjork.

    1. I microwaved 4 cups of water, and dissolved 1/4 cup of soda ash in it.
    2. I poured all of that in a plastic tub, and after squeezing all pre-wash rinse-water out of the cotton, I soaked the cotton in the soda ash water.
    3. Meanwhile, I dissolved 3/8 tsp urea into 1/8 cup of water. I added some of that to 1/4 tsp dye and pasted it up. Then just said screw it and added the rest of the urea-water before pouring it carefully into a squeeze bottle.
    4. I squirted the dye onto cotton, then gave it a nice little massage. 
    5. I put the cotton in a vegetable bag, and squeezed out all of the air, then put that in a sealable freezer bag. I left it in the backyard, hoping it would stay warm, although I'm not sure if exposure to the sunlight was a bad idea. Anyway, I forgot about it for 24 hours before washing it with PTD again.


    Results and Conclusions

    Neither of the methods produced Deep Orange. Unfortunately my camera phone doesn't convey the results accurately, so you'll have to trust me that the direct application method produced deeper, brighter, more saturated color, and it was also easier and less messy. It's so annoying, I'm looking at my dyed fibers with my own eyeballs right now, and the difference is so obvious. But they both suck, so maybe the true color not showing up great in these photos doesn't matter.
    Top: Tub Dye Method
    Bottom: Direct Application Method

    Look at the lighter regions of the fibers to understand what I'm trying to convey here. The shaodows make the fiber look more saturated than they are. Tub dying produced more of an Orange Sorbet while the direct application almost exactly matches Orange Crush.

    Yeah, yeah, it's still pretty, but it's not what I was going for. As it turns out, if I had done a little more research ahead of time, I would not have been so surprised. Leigh's Fiber Journal tried pretty much the same thing with the same materials and produced the same weak-ass results.

    It's not like I went into this unprepared either. I did research and made careful calculations based on the dry weight of my fiber. However, the amount of chemicals I used came from recommendation for cotton items that have already been woven or knitted. Perhaps the core of a thread is not completely penetrated by the dye bath, and here I am trying to dye every single fiber, like an idiot. Why the hell do I want to do this again? If my hunch here is true, then that means I must increase the amount of dye per ounce of cotton lint. That seems a bit wasteful.

    Another thing I learned recently is that soda ash doesn't just interact with the cellulose fibers, it reacts with the dye particles too, rendering them gradually less effective over a short period of time. Because of this, your dye bath will never be exhausted or clear as in acid dyeing in wool. You will always have some shitty dye particles left over. I don't like that, not only because it's wasteful, but because that seems pretty crap environmental-wise. The reason I have been so careful with measurements has been to eliminate waste as much as possible.

    For the next time, I've got some changes I'm considering. Primarily, I need to use more dye. When I started this project, I calculated the amount of dye needed based on the dry weight of the fiber. I'm beginning to think that the amount of cotton isn't all that relevant to calculating how much dye you need. I have a hunch the concentration of the dye being applied to however much fiber you have is more important. This is why I'm also going to try to dry out the fibers between pre-washing and dyeing. In both the tub dyeing and direct application methods, the fibers were pretty well saturated with liquid before applying the dye, which may have caused the dye to be too dilute for good results. Why this doesn't seem to matter with pre-made articles of clothing or yarn currently evades me.

    There were some challenges with physical properties as well. The clumps of cotton are difficult to break up without forming unusable rope. These clumps also form air bubbles which prevent the fibers from coming into contact with the dye. Moving forward to address this issue, I will be doing a craptacular job of combing the cotton into some rough roving-like logs. Hopefully this will make the fibers more available to the dye without me having to stir up the fibers and tangle them.

    Everyone else in the world who felt like dyeing cotton lint would be neat-o is probably just going to be happy with their pastels, and that is fine. For me personally though, things are going pretty well in my life, so in order to keep my karma balanced, I feel like this is a pretty safe thing to stress myself out about.
