If you pre-wash your fabric before using, do you add detergent? I always pre-wash mine because I don't want to find out later that the colors runs, and because if it's for a garment I don't want it to shrink! But is there any reason those things can't be achieved by simply letting it soak in warm water for a few minutes, without detergent, and then letting it drip dry or tossing it in the dryer?
