I would like to be able to attach this frame to the side of my house
temporarily (a few hours at a time) without leaving any marks on the
wall.

I realize this seems impossible, but this group has come up with some
amazingly clever solutions in the past, so I though I'd give it a
shot. I can add things to be back (PVC side) of the frame, but not
the front.
