Actually, they don’t rock. That’s the point of them. Check out Beehive Hangers here. They’re these uber-cool picture hanging hooks, and honestly, they are the best thing to happen since sliced whole-wheat bread. :O)
I saw them a few years ago on an HGTV show or something, ordered a sample, and fell in love. Now I use them whenever I can to hang things.
Even more good news about Beehive Hangers? It’s this small little company with superior customer service!
