I recently ordered some flannel for baby receiving blankets & burp cloths from Thousands of Bolts. It was good quality, good price. All shrank some in pre washing and drying. If I was going to cut it into pieces to make blocks I would have shrunk it one more time just to be sure. I also made 1 blanket from a cute Joanns flannel that I couldn't resist. That flannel is much lighter weight, shrank lots more and I think will pill.
