I can see pre-washing for quilts or for other projects what will be washed a fair bit, but what about making purses/totes? I have been making lots of them, and have not pre-washed the fabrics. I also like working with them when they have some body, but hate taking the time to pre-wash and starch etc. When I get a new fabric, I want to start cutting - NOW!! Do others on the board who make totes and bags for sale, pre wash??
