I have done several pieced cotton quilts with flannel backing and Quilter's Dream cotton batting without any problems. I pin baste and use Aurifil cotton thread. Most of my quilts have been for grandkids so like the soft flannel backing. I have also used Minky for backing that has worked well, also. Haven't used fleece so far but I may sometime. I do FMQ, not straight lines and so don't use a walking foot, although my machine has a built in walking foot, but that's not for FMQ.
