I still like the recipe I found here on the board a while ago (Recipe to Keep Colors from Running). I have a top loader and this works quite well. I let the washer run for a minute or 2, then pause it, add the recipe and color catcher and it works pretty well on all my quilts. I use mainly batiks and if I have dark colors, I use several color catchers. I have not had any color bleeds into lighter fabrics.
