There is a controversary concerning washing fabrics before quilting with them. One opinion says to not wash them, so the sizing is left in. It's easier to work with. The other opinion, of course, says wash and iron everything. I've tried both, and I'm one of the weird ones in the minority who likes UNWASHED fabrics. I've never had a problem with shrinkage, color fading/bleeding, or anything that distracts from the finished quilt. So don't worry about it! Definitely don't wash anything before quilting, or you may end up with a raveled, thready mess. I"m sure that I'll get lots of messages saying I'm in the wrong about not washing, but I stand by my favorite. Just enjoy your project! S.
