Beautiful wall hanging, you did a fantastic job. How about mounting it on 1/4 inch plastic core board, like the stuff they make for organizing your fabric. The boards that you wrap your fabric around and can then stand them up on a shelf. This would give the quilt stability without adding weight. Attach a 3M hook on the back and then hang. This would display your work, wouldn't weigh a lot and shouldn't make a big hole in the wall.

Or - thin sticks like you would fly a kite maybe

Like DottyMo suggested- put them together just like one does when putting a kite together. Looks great.

I actually use the command picture hanging Velcro strips, cut two in half and Hans so ew the bottom half onto the top two corners than put the other part one and stick it on the wall

I use this on all of my small quilts and when you want to move them you just pull it off the wall no damage

Believe it or not I just staple my quilts to the walls. The staple leave such a small hole it is barely seen. That way I can staple the corners down so it lies flat on the wall.

Command Strips are a great idea! I never thought of it.

A friend of mine has a company that makes a hanging system especially for quilts like this. Check out : www.gonesleeveless.com

I have a wall hanging I modified from a Christmas tree skirt. I had a flat top, but the points would sag. I sewed a small piece of velcro on the offending corner, then placed a piece of Command strip velcro to the wall. It won't hold up a whole quilt, but those points stay flat!
