After you have sewn the binding on one side of the quilt, flip back the binding from the seam, put fusible thread (called Thread Fuse) in the bobbin and sew a 1/4 zig zag along the quilt edge. Then flip the binding over and press down. This will keep the binding in place so it's easy to machine sew or hand stitch. I've done this so much I now just do a zig zag stitch along the edge with regular thread that gives me a nice flat edge to flip the binding over.
