I have been making 8x10 contact prints by putting the negative and paper together then lying a sheet of glass on top. No matter what I do, the negative and paper always get a little out of alignment. It is such a PITA. I have a contact printing frame for alternate processes but it is a bit of a hassle in the darkroom. I don't really need the "trapdoor" in the back for normal contact printing.

So my question: is there a commercially available contract printing frame that would keep my neg and paper together, or do I have to build one. I was thinking of just gluing three strips of plastic to a sheet of fairly heavy plastic. The strips would hold the neg and paper in place on three sides and I could just place a piece of glass over it without moving everything around.

Or is there something even simpler and obvious that I am missing?
