In other words, don't store your quilt in the freezer!!!
:lol:
I would test it, iron it out, throw your test in the freezer and see what happens. If it does reappear after the chill, try washing a sample after ironing and freeze it. Better to be safe than sorry.
I am watching to see if this will really work, cause if it does, I need some of those!!!
