I dye 8 different types of yarns in weights from lace to bulky. All but one are grown and/or spun in the United States or Canada, which helps to keep their economic and environmental footprint as close to my home as possible. I dye both non-superwash and superwash yarns and believe both have a place in a knitter's stash and for different knitted items. When making garments, I lean toward using and recommending non-superwash yarns because the yarn retains memory of its original crimp, which helps it spring back into shape after washing and wearing. The yarns I dye are the actual bases I prefer when knitting, and they reflect my preferences for plump, round yarns (most are 3-ply), natural fibers, and production that's close to home.
