The hook you see is a regular Christmas ornament hook latched onto two ornament toppers that I hammered through the poster board and taped in place.
The door handles are made out of two slivers of cardboard cut from the packaging of the tape I bought. I folded each end and taped them on also. I think I will probably decorate them at some point, but this was an easy inexpensive way to keep my kitties off my shelves. its been almost two weeks and the tape still holds.
