Yes, I've used them often. Especially on baby quilts. (There is a picture of one on the thread, "Looking for help to make baby quilts for the NICU, neo-natal intensive care unit" on post #133. It is the one with the mommy and baby pals and yellow boarder. You cant see the backing, but I did FMQ and you can see there was no problems. For babies there is no slippage, and it is similar to baby wraps that they love. I had no issues with FMQ. I did spray baste and thought that was important with this backing. If the flannel is a good price, I say go for it.
