Denise: I didn't know that Fabric.com offered this item. I think it is a really neat idea but like you I am a prewasher. I don't think that having a prewash front and a non-washed back would create problems. The manufacturer knows it won't be washed any shrinkage should be absorbed between the quilting. Maybe you could call the store and ask them. Just some thoughts. Without a doubt someone more expert will have some info. I'll be watching.
