I work almost exclusively with silk acid dyes for painting and dyeing silk. When I paint, I mix the dyes with water and apply with a brush to stretched silk (or not stretched, depending on the effect I want). Painted pieces, as well as various low immersion and tie dyed techniques, require the acid dyes to be steam set as the final step in the dyeing process. I don’t have a professional silk steamer, but here is my super low tech way of doing it.
