I am a pre-washer. If I even think a fabric will bleed, I soak in HOT water with Retayne, for about 4 hours, rinse, then I wash with a little detergent and a color catcher on mild cycle, for a couple of minutes, rinse, dry on hot, take out of dryer, when almost dry, fold until ready to use. I don't press anymore, until I am ready to use. This is when I have looked all over for the perfect fabrics for a certain pattern.
