To hang my wall hangings I make two squares (about 3 or 4 inches), fold them diagonally, and stitch them to the top corners of the back of the hanging as I put the binding on. Then I can cut a small dowel and insert it in the two corners and hang it from that. It has always worked great for me. You might want to baste them in before you add the binding so you don't have to worry about the stitching catching them just right.
