I'm just getting around to washing my stash so that I can get it put away for baby. I have a mix of all different colors of diapers. The ones that are bright colors recommend washing separately 6 times to avoid color bleeding. How well do I need to separate them?? Does each color need to be washed separately? Or can blues go with greens, reds with oranges, etc? I don't want to ruin my new dipes! TIA!
