Ok, I have a very big Superman puzzle...one of those with foot wide pieces. I want to put it on my sons bedroom wall. I can't figure out how to put it up there. Is there a way to put 2 pieces of plexiglass together and mount that? If so, how is that done? I thought about putting each piece on a frame and hanging them individually, but I don't think that exploded look is what I'm going for. Any ideas? TIA!
