I've been dying to dye my own yarn for months now. I've been a knitter for many years and the beautiful yarns that are available now inspire me to create my own. I finally did it, and documented the process here.

All items used here should NOT also be used to prepare food.

Materials you will need:
Yarn - I got mine at Dharma Trading, 75% wool, 25% nylon fingering weight (sock yarn)
Dye - I used Jacquard Acid Dyes
Distilled white vinegar
Synthrapol (available at arts & crafts stores; I got mine at AC Moore) or Dawn dishwashing liquid
Dust mask
Gloves
Small tub for soaking
Colander
Plastic wrap - my sources recommended brand name (thicker ply)
Measuring cup
Measuring spoons - plastic or stainless
Little containers for the dye
Sponge brushes
Sprinkler or spray bottle
Microwave oven (ideally an extra one, not one you use to cook food in)
