Pale doesn't necessarily mean boring - more Procion MX experiments

I have been doing Susan Purney Mark's class Shifting into Neutral. This is radical stuff for a color freak, but there's a place for gentler colors where texture really comes into its own. I'm very much liking the color play across this one. For me the trick is to get light areas that aren't just white cloth. It's a fine line!

Dye color chips - storing a record of dye experiments

Don't you hate it when you have a brilliant idea that turns out to be a dud? One of my new year's resolutions was to have less trash leaving the house. Consequently, when I wanted to create "paint chips" from my dye samples, I turned to my ample supply of trash cardboard. Political adverts on good card stock, the cardboard sheets that separate cat food cans, etc. etc. I had cardboard in spades. I spent an afternoon carving it up into usable 2" squares, neatly shaving off a piece of my finger in the process. Apparently scalpel means sharp.

I wound about 40 fabric swatches before the father of the artist reminded me that the artist would strongly disapprove of this project on the basis of acid in the cardboard which would discolor the fabric over time. I suggested that next time he might say something sooner...My recycling project lay in ruins. Then I remembered that I had some 50 sheets of stiff vinyl I bought to make stencils with my Cameo. That endeavor ended in a lot of bad language and leftover vinyl. Recycling back on!
"Paint chip" MX dye samples - fluff from batting
There are lots of pictures of people online who make wonderful color sample books, gluing intricate little squares into clean, white pages. I'm pretty sure that if I tried that it would look like a glue factory had exploded across Pigpen's sketch book. Plus I like to play with my color swatches, I don't want them nailed down. Also, when you do low water immersion dyeing, the range of color across the sample can be quite dramatic. If you are were going to pick a little square to represent the dye experiment below, then which little square would you choose? For me it makes more sense to be able to see the range of color across the fabric.

Previously I pinned my samples onto poster board that had been covered with batting. I lost the feeling in the tip of my finger for about a week after all that pin pushing. The problem was the poster boards took up a lot of space, and the cats took great delight in pulling the samples off. Also, the batting deposited gobs of fluff on the samples.

New plan: roll the strips around vinyl (which is awful for the environment, I know, but this was already bought and paid for, so might as well use it, right?) and secure with tape. There may be some discoloration around the tape over time, but it will be very limited. Also, no more pin holes

These dye chips can now be stored in a much smaller space. I can pull them out and play with them as 2" chips, or I can open them up and see the full range of color across the sample. The "recipe" is written in indelible ink on plain muslin, fused to the top of each sample, and cross-referenced in an Excel spreadsheet in case I drop the sample into a different color...true story....Each sample also has a unique number on it, so I can easily put them back in the drawers when I am done playing. The chemist and I spent several days sorting the colors. It was quite satisfying once, and would make me crazy to ever have to do it again. Colors I particularly liked are named and easily identifiable with a large paper clip. Not as pretty as those sample books, but more suited to my way of working. 
Some 2000 samples now fit into 4 drawers
And the cats do not have opposable thumbs so they won't be able to get into the closed drawers. The day cats evolve opposable thumbs will be a bad day for human kind, and quilter/dyers in particular!

Ice-dyeing - results

Many of the results were blah so I won't bore you with them. 

Here are the ones I was somewhat pleased with:



t shirt ice-dyed with Procion MX
This was scrunched. The fat quarters I scrunched were just blah. Maybe this was big and dense enough that the dye ratio to fabric was good, and there was space for the color to spread and blend.

Fat quarter with 3 pinch twists. Reminds me of a sunflower somehow!

Shibori ice-dyed style. Very different from normal dipped shibori!

I finally got to play with the new Procion MX pure grey. Results next time.

Overdyeing experiments - part 3 - some fabric pics at last

My goal in overdyeing fabric was to create more nuanced colors which I would like to explore further in various ways. I am mostly drawn to clear bright colors, so this wasn't an exercise in exploring neutrals. However, there is definitely a place for more subtle colors and neutrals. Helen Terry has some great posts on neutrals overdyeing experiments with complementary colors, and she has some truly lovely results.

My experiments are not rocket science, nor do they produce startling new information, but I find it helpful to document what I find as I experiment with Procion MX dye, and perhaps some other new dyers will too. Here are the conclusions I drew from this exercise:

1. It's all about proportion. Mud is not a foregone conclusion whenever the 3 primaries meet. There were some complementary mixtures which made pleasing colors where the proportions were not 1:1.
Base green/overdye red = ick
Two perfectly pleasant greens (top) which become extremely ick when the overdye contained too much red (bottom). Trust me, this photo is flattering those overdyes. They are butt ugly.

2. To my taste there are more positive results when the base range is analogous to the  overdye.
Base yellow/overdye analogous = all good results
Teal and pink overdyes (bottom) are not strictly speaking analogous, but far enough from complement to produce some very pleasant colors. 

3. The overdye which was successful across the greatest range of base colors was a pure blue. Further tests needed to determine if this was because it was blue, or because it was not a mixture. All the other overdyes were mixtures of pure colors (except the dirty green, which had grey). Almost all the base colors were mixtures of pure colors.
Blue overdyed with indigo
However, even in mixtures the blue played nice. This medium blue (left) is a mixture of 4 different colors, overdyed with indigo (red and blue), on the right. The base blue makes for some lighter pops of color creating a nice varied result.

4. When working with mixtures it is really important to keep in mind what makes up the mixture in order to have a successful overdye. Green made from blue and yellow will introduce very different elements than a green made from yellow and black.
Overdye surprise!
These little pops of turquoise are not turquoise dye, but blue overdye reacting with the  yellow which separated out in the red mixture. The result makes for some stunning pops of unexpected contrast.

5. Grey is a whole other ball game. There is a new pure grey that has just been manufactured, but this isn't it. This is a grey that tends to green. That means it is great with the blues and greens and teals, but turns pinks and purples a dull brownish mauve. From left to right, orange and grey - an interesting mushroom; teal and grey - never met a teal I didn't like; red and grey - unappetizing brownish mauve. Looking forward to testing with the new grey to be able to grey things without adding unintentional elements into the mix.

6. Overdyeing can rescue an obnoxious base color. Here the base color was a lime that would set your teeth on edge (bottom). Overdyed with teal (top), it becomes a much more likeable sour apple green, still with hints of lime to give it interest.
Lime green overdyed with teal
7. The respective strength of the base color and the overdye will have a big influence on the results. I dyed the base color at 4% OWG (left) and at 8% OWG (right). The overdye was at around 2% OWG. Remember the covalent bonds? An 8% dyestock uses up a lot of the available dye sites on the fabric, so the overdye was much less obvious. Some of the overdyes were made to a much weaker concentration than others. I was afraid the indigo would overwhelm if I made it too strong. The pink and dirty green were also very dilute. Where these overdyes were layered over colors similar to themselves, they barely registered.


On the 4% piece (left) you can see the mottled look created by dye sites which are not completely full. This is particularly obvious when you dye with the low water immersion method. This red was overdyed with a dilute dirty green made of yellow and grey. On the 8% sample there are barely any overdye marks (bottom right). On the 4% sample there are some interesting greeny/grey marks (bottom left).

Even more dramatic is the indigo overdye.
The 4% solution (left) allows for a strong indigo overtone in the overdye (bottom left). On the sample dyed at 8% (right) there are only traces of indigo by itself in the overdye (bottom right), although the base color has darkened considerably. 

One last point is the fabric used. Because I planned to dye so much, I went cheap and used my Joann's coupon to buy the Premium Legacy muslin. This is not mercerized, and gets a fuzzy look after a tough dye workout. If I had used mercerized print cloth, I would have had brighter results.

Lots more questions to answer! To the dye pots for more experiments!!

Procion MX overdyeing fabric - results part 1 - getting all sciency(ish)

Dyeing with Procion MX is so stable and successful because it is a fiber reactive dye, which means there is a chemical reaction between the fabric and the dye which creates a very strong bond. Unlike paint, that sits on the surface of the fabric, the dye forms a covalent bond with the fabric. If you want a good scientific explanation relating to Procion MX, go here
Overdyed fabric
If you want a quick word picture here it is (I can imagine my daughter, the chemist, rolling her eyes..): picture the fabric with lots and lots of cute little hands, fingers waving in the air. Make sure your mental picture is cute, or it starts to look like a horror movie - zombie fabric is coming to get you, run! Now imagine your dye stock also has lots and lots of cute little hands, fingers waving in the liquid.



When the dye stock meets the fabric, the hands reach out to one another and the fingers intertwine, making bonds between the fabric and the dye. The number of hands (technically dye sites) on the fabric depends on the type of fabric you have chosen. The number of hands in the dye stock depends on the strength you have mixed, i.e. the ratio of dye powder to water. While you can bump up the ratio of dye to water, after a certain point you are just wasting dye because the number of dye sites on the fabric is the limiting factor. After all the dye sites are filled, there is no way additional dye can react with the fiber and it will just wash out and down the drain.
 
Overdyed fabric
This is important for overdyeing. If all the hands on the fabric are already holding corresponding dye stock hands, the overdye color will have no impact. However, if you have used a diluted dye stock for your first dye, there will still be fabric hands without dye partners and they will reach out and grab the dye hands of the second dye stock.
Diluted base colors overdyed
 Now I have to step away from my analogy for a moment to point out that dye is transparent. Unlike paint, which covers your first color, dye will not completely mask your first color. Moreover, the base color will influence the second color.
Neutral overdye
It sometimes gets confusing when people talk about overdyeing. Some people use overdyeing to mean dyeing a value gradient from light to dark, or dyeing a mixture of two colors from pure color A through increasing amounts of color B till the last color is just pure color B. However, what I am doing here is dyeing and washing out a base color, then dyeing a second color over the first base color.

Next post: analyzing the results of my experiments.

Preparing to overdye with Procion MX

Remember these?

These were some of my favorite colors ready to be overdyed. 

Each of these was a fat quarter, which was then torn into 8 pieces, 1 original color to keep for comparison, and 7 to be overdyed with various other combinations.


1/8th of each color scrunched into a wallpaper tray
Overdye color poured on. Panic sets in, is this a big waste of time? Will the results just be a homogeneous mess? to be continued...

Frustration-free yarn bundles for dyeing with Procion MX

Here's how to prepare a skein of yarn for dyeing so you avoid tangles and frustration.
Take 2 chairs and drape the skein of yarn over the backs of the chairs. Move the chairs far enough apart that the yarn will not be slack, but you don't want to stretch it. The demo yarn is Queen Anne's lace. It is a 100% cotton and dyes up beautifully with Procion MX dyes. I then use it for couching. 
Dye bundle tutorial 1
 Now you need a fiber that is not going to take the dye, so it is easy to see to remove when you are done. Acrylic yarn is perfect. I see you, Ms. Twitch, leave it alone!
Eyeball the yarn and tie a piece of acrylic yarn in two equidistant spots. Notice how the tied pieces are by the chair backs. I am going to be working in the open area between the two chairs.
Dye bundle tutorial 2
Take as many strands as you feel will be comfortable for dye batches. I find 10-15 strands is a good number to work with, as I can be sure the dye is squished into all the strands. Nothing worse than finding white patches when you are done. Tie a piece of acrylic yarn around the strands you have chosen. You can use a simple double knot. Separate another group of strands and tie them together. 
Dye bundle tutorial 3
Tie them loosely, so that you can insert the tip of your finger into the knot. If the knot is very tight, you risk the dye not being able to get to the fiber.
Dye bundle tutorial 4

Continue until all the fiber is tied off into batches. When you are done, move the yarn around a little, and you will see if there are strands you have missed.
Dye bundle tutorial 5


 Now do the same on the other side of the chair. You should now have the yarn tied in 4 places. If you think of the skein as a square, then 2 opposite corners should have a single tie, and the other opposite corners should have multiple ties. 
Dye bundle tutorial 6


Ms. Twitch is doing her best to undo them all, so we will have to move quickly! Now comes the scary bit!
Dye bundle tutorial 7
Cut the entire skein at one of the single ties.If you wanted longer pieces, you could only separate out the threads once, and only cut once. You would then have yarn the full length of the skein, but it would still be separated into bundles.

I prefer to hand couch, so I like lengths half the length of the skein. I am therefore going to cut again at the other single tie. I now have neatly bundled yarn, ready for a soda soak and dyeing. See this post. 

Having been scolded for being obnoxious, Ms. Twitch is now feigning indifference to the whole process. Do not be fooled...
The less untangling you have to do, the more time you can spend dyeing, and that's what we are really interested in..color, color and more color, and the ability to blend hand-dyed thread and hand-dyed fabric, and have fun!

Making fabric scraps into useful donations

Unwanted fabric, big and small is a problem for lots of crafters, quilters etc. The stuff piles up! My son's college had a sobering labeling system for garbage. Cans read either "recycling" or "landfill". Yikes! It's so easy to toss stuff in a garbage bag and not think about what happens to it after that. 

So, I have scraps large and small, thread up the wazoo, not to mention UFOs that are never going to get finished because I either screwed them up too badly to make it worth the time to fix them, or I really hate them. Leah Day had a thought provoking post on what to do with unwanted fabric, and it didn't take much investigation to find out that my local quilt shop collected pillows stuffed with all the unwanted soft stuff, and donated them to the local animal shelter. Done deal!

I can't tell you how therapeutic it is to take a rotary cutter to really ugly projects, or projects which have driven you to distraction. And when the end result is something that will provide a little comfort to a homeless animal, well, it positively makes your halo glow, and takes away all the guilt so often associated with UFOs!

All you need is some kind of container for your pillow, to support it while you are filling it. I have a rectangular basket which I keep next to my sewing machine, so it's really easy to dispose of all those threads. 

Then you need some fabric for the pillow casing. Obviously I do not use my rather nice hand-dyed shibori, this is for demonstration purposes only! I normally buy fleece when it is on sale, as it is so nice and snugly. Lay the fabric out, then fold in half, right sides together. Sew the 2 short ends closed and turn it right side out.

Remove cat from fabric and line basket with it - the fabric, not the cat. 

In a shockingly short period of time the pillow will be full of threads, trimmings, free-motion practice strips and the like. If you are feeling kind, buy some cheap batting and slice a little into each pillow for some extra softness. Check for stray pins. These will not add to the comfort of the pillow!

Not your average pretty blog picture!

Dangling threads are a great temptation. You may have to rescue some which have mysteriously left the basket.

Make sure the pillow is not so full that it is no longer soft, then sew up the long open end. I just zigzag it closed. Your scraps are taken care of, you have a nice soft pillow for a needy animal, and the effort involved is minimal. Thanks for spurring me to action, Leah!

No longer threadbare!

Procion MX continues to rock my world with color! I love to add hand embroidery to my fiber creations, so what could be better than dyeing my own thread? Quilting Arts Aug/Sept 2014 had an article by Melanie Testa and Carol Soderlund on dyeing your own thread. I bought the thread winders they recommended, but when I came to do the dyeing, I couldn't find them. You know how that goes...But it was all good, because I like my way better, although there is some winding and untangling at the end.

Once my dyes were mixed and my fibers were soda soaked, I took some trusty plastic shelf liner and added three generous dollops (very scientific term..) of analogous colors towards the back of the plastic. For more complex colors I added black or grey. Then I laid the skein of thread closest to me on the plastic. With gloved hands I then drew beads of the dye down to the fiber, mixing the colors in some parts, keeping them pure in others. It is so fascinating to see them blend and change, and this way I could get a lot of color variety because I could adjust the length of the fiber strands. I have several sets of lidded plasticware for batching, and I also used them for soaking each color set in water to get rid of the excess dye when the batching was complete. Three days of changing the soaking water and the dye was gone. The hardest part was getting them dry! They are more tangled than usual because I got impatient and threw them in the tumble drier in garment bags. Luckily my daughter is almost as obsessive as me, and will join me in a winding and untangling fest! Grown up daughters are the best! So companionable!

Once dyed, the threads can also be overdyed, providing you haven't saturated the color receptors the first time around. Great for couching, embroidery etc. Yarn is from Dharma Trading.
Procion MX dyed cotton yarn


The first time round I added a reasonable amount of soda solution, but didn't cover submerge the fiber, and when I came to add the dye, it didn't penetrate all the way in some places. The second time I completely covered the fiber in soda solution, expecting to be able to drain off the excess, but it drank it all in! Greedy stuff. You could probably soak it in water to get it saturated and then just add the soda ash you need for dyeing. Once wet, the dye seemed to travel fine. This yarn takes forever to dry too, but is very rewarding once it is done. The first yarn pack I bought, I cut it into lengths suitable for couching or embroidery and then dyed half in oranges/corals/pinks and the other half in greens. What was I thinking?? These are big packs. No one needs that much green! Luckily it overdyes beautifully. This was a desperately boring pale lilac, but not anymore! Some of the green is now teal and turquoise.



I had so much fun with the first yarn pack, I then tried the shahrazade. Clearly I should not enter spelling bees, that is a word with waaaay too many letters! This yarn has rayon slubs, which also dyed beautifully. The more prosaic thread is DMC 8.

Lots of fun, and not difficult at all! Give it a shot! (If you haven't used Procion MX dyes before, do some research and make sure you use safe practices. Paula Burch's website is a fount of information )
