Silk Dyes, as opposed to paints, leave the silk as soft and pliable as the original fabric. Dyes, however, need to be "set" to make them permanent. Professional silk painters steam exclusively.
Steam Setting is a process that results in colors even more vibrant and permanent than chemical setting. But there is a learning curve to successful Steam Setting. My Steamer is now here on site, so steaming classes are now available. I could also steam your home paintings for you. Call me for details.
