I use decorative clips that you can get in the department store with the curtain rods. There are usually 8 to a package and they look a lot the ones you use on shower curtains except there is a clip on it.
I put sleeves on all my quilts in case whoever I give it to wants to hang it up. It is not hard to do. Even if I am going to hang it with clips I put a sleeve on it.
