Sorry to do this to ya'll but I have a puzzle question. I know how everyone hates puzzles. Customer brought in 2 puzzles done as a marketing tool for their company. Puzzle is kept together with tape on the back. No glue. Looks like some type of wide packing tape. I don't trust this tape to hold the puzzle together although it seems adhered adequately for now. How do I mount the thing? Spray mount will probably not adhere to the tape, do you think? Can I modge podge on the front? Laminate it?
