Barb, I usually don't either. In fact, many of the quilts I make are OBW's, and you're not supposed to prewash for those. But lately I've been thinking on two things: I'd like to make more accurate quilts, and I'm getting a lot of lint in my sewing machines. A TON of lint. So I'm trying something new. :-)
[QUOTE=Barb in Louisiana;6827119]Amazing that I am the first to post that I don't wash my fabric before piecing. I usually don't need to starch because the sizing from the mill is still in the fabrics. Of course, sometimes I do get surprises when I wash the finished quilt. :
