Ruth,
I make my wall hanging just like a regular quilt.
I don't hang them according to protocol though. I use a staple gun! I just staple those babies up and I tack the bottom corners as well. Hey, it's my quilt I can poke holes if I want to! Right?:mrgreen: It works for me!
Actually, I have a couple that I've hung with tacks. The bottom is hanging free. They look fine. The very small quilts that I display on hangers hang straight with no problem. I think as long as your quilt will lie flat it will hang that way also.
