These powdered dyes are intended for vat-dyeing yardage, yarns or clothing. They can also be used for painting but they're not our first choice. If you intend to paint on silk or wool, choose one of the silk dyes from elsewhere in the catalog. You can use these dyes either on top of your stove or in a washing machine but they do require very hot water to work properly. The only other thing needed is a little white vinegar from your pantry. Acid dyes are very economical, as they react fast, they exhaust well and the results are Very Permanent- light and wash fast!
