I have a lot of prefolds that I want to dye solid colors. I've bought the dye- Rainbow rocks from Michaels, but it's a tye die kit. I'm going to need A LOT more dye aren't I? Do I dye the prefolds in the sink, in buckets outside? I'm sorry for the really stupid questions, but I've never dyed anything before. Please help. I need a "Dying for Dummies" book LOL! Thank you
