I decided to dye all my flats and prefolds with the dyes I bought like...a year ago. I followed the directions on the Dharma website and it turned out fabulous, for having one nice uniform color. But I want to try multiple colors like I've seen for sale online (for way more than I can afford to spend on one diaper) and am not sure how to do it, or even what it's called. Not tie-dyed but when they have the beautiful mixed swirly colors. Anyone want to help a clueless newbie out? I'd really love for my new son to have some gorgeous diapers since we're not doing fitteds this time around. TIA!
