I made some quick quilts for my toddler boys that had no batting and fleece backing. I was going to tie it but got too lazy and used the button stitch on my machine and randomly tacked the fleece to the quilt top. These quilts get tons of use and washed all the time. I've had one seam pop open (one was pulling the other one on their "quilt sled"). They are super warm and lay nice and flat.
