I, for one, cannot believe that so many of you on this board, do not pre-wash. The first thing I was taught was to pre-wash any fabric that I bought when I brought it into the house. We have no guarantee's on ANY fabric we buy and the safest way is to pre-wash. That way I never have any surprise's like yours. I am so sorry for you. What a nasty way to learn that lesson. Good luck to you.
