PRO WashFast Acid Dyes are designed to permanently dye protein fibers -- animal fibers like wool, silk, angora, mohair, alpaca, soy silk, and nylon. They have excellent wash and light fastness properties. All colors intermix well and dye with a minimum of salt and acid.
Two ounces of dye will color 12 pounds of wool to a medium shade.
