I was dying my jumpsuit with blue dye (the first attempt came out too purple) and before dumping out the dye (Rit Royal Blue) I decided, on a whim, to toss in my roll of hose for a while. It was the kind you get at Home Depot- clear, with the criss-cross pattern of reinforcing threads running through it. After about three hours, I pulled it out, and it had taken the dye beautifully! I rinsed it out well, and hung it to dry. After it had dried, I took a wet white rag to it, to see how permanent it would be. I scrubbed it for a few seconds, and the rag didn't stain a bit. The color is too bright a blue, of course, but I'll add some black and throw it in for another soak. Pictures to come.
