Thank you all for your input. I'm still undecided on what to do though. I don't know if people are going to want to buy a panel and then have to buy a rod just to hang it, that's why I was trying to think of something else. I don't think that triangle thing with a ruler and command strip will work because the panel might be too heavy as I'm adding lights to them (inspired by the Starry Night Wall Hanging tutorial). I guess I'll figure something out eventually. Thanks again guys and gals.
