Fabric bleed is absolutely my nightmare. I cringe when I see the piles of my early dyes, because I know they're not properly set and I'll never use them. But now, I've upgraded to Procion Dyes, and I go through a multi-step process of scouring, soda ash, dyeing, multiple rinses and soaks before washing, so at least I know these are set well! And thr color pallet I'm using thankfully excludes turquoise, which seems to be the most stubborn Procion dye to set.
