I did the curtain rod ring thing with a larger wall hanging, but I actually just used a 1" dowel and put those balls w/ one flat side on each end (I put the rings on the dowel before gluing the balls on) and then use two nails in the wall to rest the dowel on. DH is very anal about putting nails in studs and never using anchors if possible and this way, he could put the nails wherever he wanted because the rod just rests on them-so it can be slid back and forth quite a bit.
