Use these dyes for dyeing protein fibers like Silk, Wool, Nylon. Acid dye is the best one for tub dyeing silk a solid even color. The Fluorescent yellow dye is also an Acid dye, and it glows in ultraviolet (black) light. Dharma Fiber Reactive Procion (the most economical) can be made into an "acid" dye by simmering it with vinegar for silk and wool, but colors can shift.

Excellent prices, bulk pricing, handy 2oz size. 52 beautiful, vibrant, and some very hard to get colors! Can be painted on as well.
Cons: Needs hot, almost simmering, water to use or needs to be steamed. Some colors take more advanced dyeing technique.
