How to Glue a Puzzle to Make a Picture
- 1). Slide a piece of cardboard under the completed jigsaw puzzle and transfer both to the cutting mat.
- 2). Cut the cardboard around the jigsaw puzzle to create a frame that will keep the puzzle from shifting during the gluing process.
- 3). Cover the entire work surface with newspaper. Slide a second piece of cardboard under the puzzle and place another piece on top of the puzzle. Carefully flip the puzzle and transfer the puzzle-cardboard sandwich to the work surface, with the puzzle face down. Slide out the bottom cardboard and take off the top cardboard. Place the cardboard frame created in Step 2 around the puzzle.
- 4). Spray glue on the back of the puzzle.
- 5). Place the stiff paper backing over the glue and smooth out any wrinkles. Cut the paper backing to the exact size of the puzzle with the knife.
