Did you know many invasive plants can be used as natural dyes? There's no guilt about peeling off the bark or pulling up the whole plant to make these dye baths! Students will learn plant identification, a bit of natural history, and how to use these otherwise undesirable species to create beautiful colors. Experimentation will include the use of modifiers and mordants and several different methods for obtaining colors. Each student will go home with a 8 different dyed skeins, approximately 30 yards each. The instructor will provide yarn and all dye materials. Students should bring a plastic bag for samples.

Beginner and experienced natural dyers welcome!
