I prewashed Bali Pop jelly Ross by gently placing them in a sink of hot water and Retayne. I just swished them gently a time or 2 then drained the water. It took several sinks of water before getting rid of the excess dye. I spun them out with a salad spinner than hung them up to dry on a clothes rack. Then pressed. Had very little fraying. Thanks for the heads up. I'll be staying away from charm packs from now on, especially if they contain reds. Count me in the pre-wash category.
