Wet nylon velvet and silk satin yardage ready to go into the microwave. The nylon velvet will dry to pastel shades. I used rayon dyes on the fibers in Olivine, Antique Gold, Victorian Rose. Some of the velvet was brown or mauve and over-dyed, which adds more of a vintage flair to the finished product. I normally microwave everything for 2 to 3 minutes and then air-dry. I do not rinse the fibers when they come out of the microwave. Fibers can be gently hand-washed or dry-cleaned but as a rule I do not machine-wash any of my hand-dyed fibers, since I use them for embellishing. All embroidered wearables are dry-cleaned.
