I've done fmq with all of these and had no problems. I have come to love doing baby quilts with a fleece backing and no batting. I just pin baste, I've also spray basted. You have to be a little careful so the fleece doesn't stretch as you move the quilt around, but it's just a matter of getting a feel for it like any other quilting. It's really not problematic on a small quilt. The cotton top tends to stick to the fleece which helps.
