Here is the kit I purchased from Pro Chemical & Dye:

It has enough ’stuff’ to dye 30 fat eighths in pastel colors (each dye packet is mixed with 4 cups of water):
Instructions
Dye A - Old Rose
Dye B - Camel
Dye C - Stormy Grey
Dye Activator (Pro Chemical’s answer to Soda Ash)
Synthrapol (I use 2X ultra all® - free & clear)
Soften It! (I use Ultra Downey® - free & clear)
So, how do you get from beige to rose or dusty violet to blueish gray? Just add water!
I weighed out half of the dye (I do not intend to dye 30 fat eighths and I needed some dye to show you some neat stuff) and mixed it with 2 cups of water. I brushed some of the mixed dye on a piece of watercolor paper to show how different it looks from the dye powder:

Then, I put 1 teaspoon table salt in each of three shakers along with about an 1/8 teaspoon of dye.

Mixed it up real good. Screwed on the cap and sprinkled each over a dampened section of the watercolor paper. I covered half of the section and spritzed it with a fine mist of water to help it dissolve even more (bottom portion of image above the shaker).
Then I threw a piece (wide fat sixteenth) of fabric in some soda ash solution (about an hour), flattened it out and sprinkled dye on it. Here’s the finished product:

Looks a lot different from the mixed dye. Here’s a close up showing the pure dye components of each mix:



What would you ever do with it? I used fabric like this here, here and here.
Mixing Dye or Patience is a Virtue - Part One
It’s old clothes, safe place, gloves and face mask time! You may not feel like it, but . . .
Think cooking. Think gravy. Think a flour paste or roux to thicken your gravy. You add a little water to the dye powder to make a smooth paste so you don’t get lumpy gravy. Then slowly add more of the water so the paste gradually becomes a syrup. Keep adding and stirring until all of the water is mixed with the dye.
You may want to make the paste/syrup in a smaller container which is easier to handle.
- Small container - a least 1 cup capacity
- Old teaspoon or one of your measuring spoons
- Larger container with the correct amount of water
- Another large container which will hold all of the dissolved dye
Put the dye in the small container and add a tablespoon or so of the measured water. Make the paste and then the syrup as mentioned above. Add more water so the concentrated dye pours easily into the empty larger container. Hmmm . . . is it all mixed? Maybe, maybe not. At least you’ll know by transferring the dye from one container to another. Use part of your measured water to rinse out the small container - want to get every last drop of dye - and add it with the remaining water. Let’s get ready to dye!
Now, here’s what I do . . . 
I weigh the dye using a gram scale in an appropriate size container. I calculate the total amount of dye to mix and use 1/2 urea water and 1/2 warm tap water - lukewarm ‘chemical water’. Too cold and it’s harder to dissolve the dye - too hot and your dye gets cooked before it ever meets a fiber. (I keep urea water on hand for mixing dye - about 2 cups urea to a half gallon of water.)
If I am mixing a cup or less of dye, 1/2 of the total amount of chemical water gets dumped in with the dye. If it’s more than a cup, I reserve 1/2 cup of chemical water. Stir it up. Some dissolve faster than others. Some need a little more stirring and coaching. When I am fairly sure most of all of the dye is dissolved, I run the dye through a permanent coffee filter into its storage or temporary container using a funnel if necessary. I use the remaining water to rinse out the initial container and flush out the coffee filter. Rinse and repeat for the next color.
Next stop - Fat Eighth City using Pro Chemical’s kit. I am going to dye 2 sets of 6. One following their instructions and the other my way. How different will the 2 sets be?
