Good Idea, at least we know the white shouldn't fade lol. Good Luck. I'm sorry it had to come to making another one, but just prewashing a fabric doesn't always get us off the hook. I'm not sure how well it works but currently when I get a new fabric that I plan to use in a quilt I have started washing it with retayne. I haven't used some of this fabric yet, but it has been prewashed with retayne, and I also plan to use a color catcher sheet. Hopefully I won't have the same problem that I've had in the past or that you just went through. Gerbie
