Plant-Based Dyes: Indigo, Madder, and Weld

If you can cultivate these three primary color plants, then you can create your own bright, natural dyes.

This vibrant indigo-dyed yarn is sold by Kerri Westlake in her Etsy shop WestlakeDesigns. The online store also contains powdered dye from indigo and madder root, and hand-dyed, knit products.
