Colorhue dyes http://www.silkthings.com/understanding_silk_dyes_and_paints.htm are being discussed on the Quiltart List, and several people wanted to see a successful piece that had been painted with them. Here's an art quilt I did several years ago for my father (who is an Erte' fan) ... "After Erte", 44"x66". The colors were quite vivid, and remain so. If I recall, I used them almost straight from the bottle, not diluting them much at all. Expensive, but worth it, I thought.
