All the ways to quilt mostly work with fleece ...depends on what the quilt will be used for. I have made tons with a fleece backing. Sometimes, just the fleece, no batting (my preferred method). You can quilt these pretty far apart, so they are soft and hugable and they last for years and years. Sometimes, I fold the fleece over the front and stitch it down with something like a zig zag or feather stitch for the binding. Sometimes I bind with a french fold cotton binding.
If you machine quilt with a long arm, a thin batting helps stablize it. I don't like that type of machine quilting as well because fleece must be stretched somewhat to put it on the frame, which makes it pucker too much for my taste. But some customers want it that way.
Have also used it as the back to rag quilts.
Just have to remember that there is a front and a back to fleece and get them right and also one way stretches more than the other. Make sure to position it correctly. Spray baste is wonderful for fleece.
Good luck!
