Natural Dyeing

I bought this book more for the information about the cleaning, mordanting and dyeing processes described in the beginning of the book. And I must say the photography is brilliant. As for obtaining the dyes, I use dye extracts from Table Rock Llamas in Colorado. They offer over 30 colors, including the exotics shown in "Natural Dyeing" (they don't sell toxic mordants). But if I want to grow my own dye plants, I rely on "A Dyer's Garden" by Rita Buchanan, a fantastic little book that gives growing info, dye recipies and results, and a supplier's list to obtain plants and seeds. Finally, I will experiment if I want to see what color a particular plant might give -- I hear bindweed, a noxious weed where I live, gives brilliant greens . . .
