I use the color catchers too. and have had good luck with them. But I did have an occassion that was not so good. I did have a red fabric that bled very badly in one quilt. At the quilting lines that touched this particular fabric turned pink in the wash. Rewashing did not change the damage from the first time. And I did have color catcher in the wash with it. So, just so you know. But one time in 5 years isn't bad odds.
