I followed the method above. Washed like colors with 1/2 a color catcher ( in a mesh bag ) thrown in to test for color fastness and used Retayne as listed on bottle in straight hot water. I kept rewashing with Retayne and a fresh color catcher each time until the color catcher came out white or nearly white. Some groups took 3-4 washings. I did not dry in between. Hope you enjoy them.
