Damkina, by all means, when you wash your red quilt, use color catchers. There are some other chemicals which were recommended on this thread -- by all means use them. My best recommendation is use a dye fixative BEFORE YOU MAKE THE FIRST CUT FOR YOUR QUILT. I've posted some long, drawn out posts on this subject. I would not wish to see anyone have to endure the distress and stress which Jane Quilter has endured. I never knew that red fabric would bleed, but it does -- I had some the first bed-size quilt I ever made (my avatar) that bled rivers. Luckily, I had the advice of my cousin who has her own quilt shop in Oklahoma. I tested the fabric -- it's relatively easy to determine a bleeder. Simply snip a 1/2" wide by 6" long strip and immerse it in a glass of hot tap water. If the fabric is a bleeder, you'll know it by dipping a WHITE paper towel into the water. If there's bleeding, it will definitely show up in the paper towel.
