How to Flatten a Warped Puzzle

Even the most complicated puzzles are relatively inexpensive, but they are more than just a way to entertain children. Putting together a puzzle is an effective way to pass time, get your mind off your troubles, or enjoy an evening with family and friends by focusing on the challenging task. It is also an excellent way to build hand-eye coordination, develop logical thinking, and increase spatial relation skills. Puzzle pieces that are warped don't lie flat and make it difficult to rebuild the puzzle later on, or to frame it in an attractive manner. Storing the puzzle the wrong way results in warping.

Things You'll Need

Large table
Plywood (optional)
Old tablecloth or sheet
Bricks, concrete blocks, large books or other heavy objects
Strong tape (optional)
Shoebox (optional)
Roll-up puzzle storage mat (optional)

Instructions

- 1
  Set the warped puzzle on a tabletop or an area on the floor where it will not be disturbed.
- 2
  Press the puzzle pieces together so they fit well if they are loose or jutting up, due to warping.
- 3
  Lie a large piece of plywood on top of the puzzle if you have one. If not, spread an old tablecloth or sheet over the puzzle to protect it from the heavy objects, particularly if you are going to frame it once the warped areas are flat.
- 4
  Set heavy objects, such as bricks, concrete blocks, heavy books or other weights on top, to press the puzzle down flat. Place the weights on the corners, in the center, or anywhere else the puzzles is warped.
- 5
  Wait at least 24 hours before removing the weights. The puzzle should be flat once you remove the weights; if not, replace the weights and leave them on the puzzle another couple of days. Frame the puzzle or take it apart, and store the flat pieces in the puzzle box. This ensures it lies flat the next time you attempt the puzzle.
