I found this on Cox and Cox, which I found via Peonies and Polaroids. I liked it a lot, but, like most people these days, I don't much money to spend on things, so I tried to make it myself.
It took a bit of trial and error. The only wire I had was floral wire, so that's what I used. I think a thinner wire would work a little better. But I'm very pleased with it!
