Can you dye yarn with liquid Kool Aid?
Cotton and other plant based fibers cab be dyed but they do not need an acid dye, they require something else. Dyeing yarn can be done with Kool-Aid or food coloring, things that you might have in your house, or you can go and purchase professional grade dyes as well.
How do you dye cotton yarn naturally?
Soak the cotton yarn in water with washing soda dissolved in the water for the mordant. Heat to simmer and continue to simmer for 30 minutes to one hour. The yarn can continue to soak in the mordant solution while the dye bath is being prepared. I use 30 grams of washing soda for every 100 grams of cotton yarn.
