Great minds think in sync! How strange you brought this up, because today I intetended to go to Ikea, but tomorrow, I should make it, to get those ever so cheap 4 pack frames @$1.99 to sell with some whimsical folk art I'm making, and I want to try several frames, so I will get a sample of the same clip frames you have. I'll let you know what I do with them... tomorrow!

But mostly likely slipping wire through and then twisting it to hang, is the best thing you can do, which is how most artists make canvas ready to hang...
