I have done a couple crib size quilts using fleece for the backing--no batting and pieced flannel blocks for the top. Both are very snuggly. I stitched around some block designs on the more elaborately pieced one--stars with alternating chain blocks and the other was a small trip around the world with 5" flannel squares so I just did an X design on it. I brought the fleece to the front for the binding. It did stretch a little on the Trip quilt but not the stars. I think the Trip one was cut wonky and I didn't square it up before I used it. I bought a bunch of fleece prints (& I mean a bunch!) on clearance a few years ago and am trying to use it up. It takes up space that I want to use for quilt backings & that's what gave me the idea to use it as backings.
