I have made a couple quilts with fleece as the backing. I used basting spray, both 505 and the June Taylor, and they both held great without pinning. I used my walking foot and a regular foot without any problems. I am not at all confident in my FMQ and just did stitch in the ditch. Turned out great! My DD freezes even in the summer so I used warm and natural in the quilt. She loves it because it is so cozy and warm.
