I took two 4-inch squares, folded them into triangles and hand stitched them on the back side of the quilt in the top two corners.
I then measured the back of my quilt from the inside edge of the bindings. For this quilt it was 31.5 inches. I went to my local Home Depot and in their crown moulding section they have 1/4" x 1-3/8" pine lattice for 67 cents a foot that you can cut yourself. You could just buy a yard stick and cut it down, but this was probably cheaper. For smaller wall hanging quilts you could even use a paint stick. Once you have your stick cut to the correct measurement, it should just slide right into the little pockets you added. Lastly, you stick on the 3M Command Strips. I used 2, about an inch in from each of the pockets.
Peel off the strips and stick it up on the wall where you like and voila! A super easy, clever way to hang a smaller quilt. If you know you plan on hanging a small quilt you can baste on the triangle pockets before you sew on your binding.
Here's the finished look.
