For smaller wall quilts (24" and narrower), I just sew a triangle ( a square folded diagonally, wrong sides together) in both top corners. If you use binding, they can go on under the binding and then they'll be sewn in by your machine. If you face the edges, you need to sew them on by hand. Then a piece of dowl or flat piece of wood, ruler or piece of a yardstick slips right in the pockets formed by the triangles. I drill a hole in the middle of the wood before it goes in the pockets made by the triangles. The brad I pound in the wall slips right in the hole.
