Recently in a quilt class we were discussing prewashing fabrics to prevent bleeding and several of us said we use color catchers for our quilts and washing more than once and with more than one color catcher in cold water. We all thought we were doing good and then the instructor mentioned that not everyone's water is the same chemical makeup as ours and it would still be possible for no bleeding to show during our wash but could bleed when washed by the recipient. What a horrible thought that the quilt could be ruined after we thought it was good. I will now test yardage for bleeding and use Retayne if needed. I will be crossing my fingers on any of my precuts I have in my stash.
