does red heart yarn dye well or at all
if its acrylic, not really.
I *LOVE* the multicolored dyes - how did you get them so that the colors didn't bleed or leech into each other? Did you dye a section at a time. wrapping or isolating the other colors in some way?
google it. you can make stripes by ssteaming the dyes to set them instead of using a crockpot. and it you dont want the colors to go into each other you might have some troubles unless u dont mind the white spot btwn the colors.
