As you're pulling those invasive species out of your garden? Try turning them into natural dyes.  In this workshop, we'll use two of the more common ones - buckthorn and tansy - to produce several different colors on wool yarns.  All materials are supplied, and you'll go home with a basic knowledge of how to create dyes and at least 5 mini skeins that you've dyed.

Taught by Theresa Hornstein. After 35 years as a college biology instructor, Theresa has shifted to artisanal research with a passion for color.  Her latest area of research combines removal of invasive species with natural dyeing, resulting in a book Invasive Color: Using Invasive Species as Natural Dyes.
