I just bought some beautiful Sheshwe's and I knew they would bleed because the blue rubbed off on my fingers. But it was the first time I have ever worried about fabric doing that so I bought Retayne and used it. What i hadn't thought about was the fact that these fabrics were bright blues AND whites.....so you can guess what happened, my fabrics now have blue tinted whites! Bummer cause not a cheap fabric. What should I have done? washed with color catchers several times and THEN used Retayne? Not sure how this would have worked but I love this fabric so much I am going to go back and buy some more and want to do it right.
