That's.
That's actually a really good idea.
I even have a couple pieces I could try it with!
EDIT: We're also looking to put a pan-hanger bar thingy underneath the bottom shelf to hang our two most-used pans and our boilin'-pot (we make soooo much pasta). That will also change the 'weight' of the shelves so I think I'll actually wait until we put that up before going crazy on the art.
