I have some clip on rings to hang things on a cafe rod. You squeeze the ring to open up the gripping device, then close over the edge of what you want to hang. These work great for me. You can find them at Walmart. Just saw some very decorative ones this weekend. But I lucked out at a thrift store a while back and got a whole freezer bag full of the less expensive type for $1.00.
BTW, beautiful quilt. I can see why it should be displayed!
