I dyed some yarn today for the first time. I have to say it was easier and less messy than I expected and overall, pretty fun! If you're interested, here's what I did (and what I might do differently next time.)
You'll need...
- One skein of yarn. I used KnitPicks bare 100 percent peruvian wool (fingering weight).
- Kool Aid. 2-3 packs of each color you plan to use. I used 3 lemon lime, 2 orange, 2 lemonade, 2 strawberry, 3 ice blue raspberry lemonade
- One quart glass jar for each color you intend to use
- Some dish cloths/towels
- A large pot or pan that all the jars will fit in
- Scrap yarn
- Rubber gloves
- Paper towels
- Collander

First step is to wind your yarn into a larger skein. Mine was about 12 feet in circumference (roughly.) Some people measure out some sock yarn they already have and like and figure out the length of each repeat that way. I just wound my yarn around the backs of two kitchen chairs and used the scrap yarn to tie it in 5 sections of unequal length.
When your yarn is tied off and ready, put a towel in the bottom of your pot and put your jars in the pot, on the towel (it will help keep them from breaking). You're going to heat the jars double-boiler style, but that comes later. For now, fill each a little over half-way with tepid water and add the koolaid.

Fill the pot with tepid water so the jars are surrounding. Now, get your yarn, decide which colors you want where and start shoving sections down in the koolaid water. Note, this is where rubber gloves will come in handy!
If you're like me and forgot that part until it was too late, a sugar/oil scrub will remove most of it!
Use a spoon or your fingers, and push the yarn down into the koolaid mixture. Turn on the stove and heat the water (slowly!).
It took about half an hour, but most of the dye will be absorbed by the yarn when it's finished. For mine, the yellow and orange finished in about 15 minutes. The water turned a milky shade, but it was obvious that the yarn had most of the dye, not the water.
The green and blue took a little longer, and the red (strawberry) never did clear up. Next time, I may try just one pack of that rather than two since it's such a strong color.
When the yarn is finished, take it off the heat and let it cool back down to room temperature.
When the yarn cools, give it a quick, gentle rinse under tepid water. Hang it to dry, and there it is!
