I made a baby quilt for a gift with batics. I tested all the fabric but didn't prewash. When the quilt was finished and it was time to wash it, I started to worry. Some of the colors were quite intense and there was white in the background. The color catchers worked beautifully, and I think I will include a box with the gift. The color catchers came out a kinda gray color. The white is bright white. Should I wash it again with Retayne?
