Thank you, ckcowl! I did not realize that there were different types of flannel. Unfortunately, buying on line, unless you are able to ask the sellers, could be a problem. I have in the past had an issue with a flannel (that I now know was only brushed on one side) on a QAYG project. I backed each block, FMQed them and then sewed them together. The flannel, which I purchased from a quilting site (don't remember which one) literally shredded at the seams. I had to put a new back on the quilt. I used Shannon Minky and then FMQed it in place.
