I like to sew around the outside edge of my quilt using a serpentine stitch before I trim off the extra. I keep it inside the seam allowance and go off the outer edge. When I trim it down, enough stitching is there to hold the fabric in place. Once in a while I get lazy and don't do it, only to regret that I didn't. It is an extra step, but it does make the binding go on much easier.
