I'd be grateful if anyone could give me a bit of insight here... I have a light green cotton perfecto that I want to dye grey or black. I heard that dying a light color to a darker shade may not work out so well, so what do you guys think? SZ recommended Procion dye, anyone here have any experience with that or any other suggestions? Also, since it's a perfecto, it has zippers everywhere, any tips on avoiding getting color on the zips? I also sorta want to cover the thing with resin when I'm done but it seems I'm biting off more than I can chew with that. Does anyone have a tutorial on resin coating for amateurs?
