Sharon, I'm one of those no washing gals. However, I ALWAYS prewash fabric from Joann's. Snuggle flannel shrinks 7-10 inches over a 7.5 yard piece. Quilt shop flannel shrinks 1-2 inches over 7.5 yards. So, don't be confused. Even if you want to go back to nowashing, do so, but I highly recommend prewashing fabrics from either Joann's or Hancocks.
I use the snuggle flannel for tied quilts. I agree with the one poster partially. Some of the Snuggle flannel pills terribly, while other colors are perfectly fine. For this reason, I use a higher quality flannel on the back of children's quilts as they are washed frequently and I totally detest that pilling. I use the Snuggle fabric on the back of scrap quilts (couch quilts or quilts for adults) since they aren't washed as often, so less subject to that nasty pilling.
