Natural Dye Source: Alkanet Root Rich Brown Color for Fabric Dyeing 1 lb Powder Form for Easy Use Ideal for Cotton and Rayon Fibers Directly Sourced from Peruvian Co-op for Freshness We have a bigger selection than ever before! Go back in history, dye something the way they did back in the day. Natural Dyes are usually used with a mordant to make them "stick" to the fabric and generally give more muted tones on plant fibers like cotton and rayon, but are brilliant on wools and silks. Don't assume that they are better for the environment - it depends - read about it first. **We are now buying our Cochineal (the little dried bugs) directly from a 5 family farming co-op in Peru who grows the Nopal cacti and harvests the little critters, so it is fresher, stronger, and less expensive than ever before! Organic too, as they use absolutely no chemicals.
