If my fleece seems thin, I use batting, but if the fleece is reasonably heavy/thick, I do not use anything but the top and fleece. Most of mine I "self-bind" by bringing the fleece to the front and stitching it down with a decorative stitch. I really try to watch when I'm picking up fleece (on sale) to get a heavier one. There is a lot of difference in the feel of the different fleeces. The more expensive ones are NOT always the heavier ones. I started using fleece on children/baby quilts but my big kids (ie. parent's of my grandchildren) really like the fleece backed "throws" they snuggle under to watch TV.
