I've been collecting flannel scraps for about six months. Whenever I go into a fabric store, I check the remnant bin. I've collected enough now for the quilt I want to make. If you can be patient, you might be able to collect enough over time. Also, fabric.com has quite a bit of flannel. If you do a search for "flannel fabric" or "fabric flannel" you might find some online. I've had good results shopping online with jofabric.com (might be jofabricS.com); thousandsofbolts.com; and fabric.com. There are many others. Those are just the ones that come to mind. And some of the people on this board might pony up too!
