I use those clips and haven't had any problems.
Another thing that I use is used larger sewing machine needles or used long arm needles. If I want to hang a small quilt on a wall (lap sized or smaller) and I don't want to use a quilt hanger I position the quilt where I want it to be and use my old needles as anchors in the quilt. I push the used needles through the quilt at the corners and tap the needles into the wall. If the quilt needs extra support in the middle, I just use more needles. The quilt hangs straight because it is supported. I do take the quilts down every so often and re-hang them. When the machine needles are removed from the wall, there is hardly a mark in the wall and I've never had a quilt damaged. But, I've not used this on a larger sized quilt.

I've done it for years, and have seen LOTS of shops do this. It works just fine and doesn't damage or stretch the quilt. But as the saying goes "Chaque a son gout". To each his own.

hanging a real quilt for any length of time is never a good thing...the weight alone will eventually put stress/strain on the seams. the binding can not withstand years of hanging from clips either unless you are able to rotate it every few months so it wears evenly.

I have wooden hangers that have a slot for the binding to fit into and then the front screws down on the quilt. But I only hand smaller wall type quilts, not a huge queen or anything that heavy!

I use the curtain rods and rings for some quilts and make hanging sleeves for others. Both methods work for me and I have never had a problem with the ring clips hurting my quilts. I have used the push pins before and ended up with small holes in my quilts.

Thanks for all the good information - now to get the curtain rod hung. First need to get rid of a very old piano that's on the wall. Anyone in the El Paso area want an old piano?
