just don't use it until you can get it to stop bleeding! I prewashed a very dark blue batik that was to be a border. The color catchers were still coming out very blue and i used the fabric anyway. Yep, you guessed it...the blue bled to some of the lighter fabrics. I was fortunate as it was for my son and he liked the look. I won't do that again. I will either keep washing till it stops..or find another fabric. JMHO
