Colla per puzzle
Many puzzles, once finished, are true works of art.After you finish one, you may want to keep it to show off to friends or appreciate what you've achieved.You can store the puzzles by applying clear glue to the front, to keep all the pieces together;furthermore, you can stabilize it even better by repeating the operation on the rear side.Once glued, you can attach it to a sturdy surface, so that all the pieces do not fall apart.
Sometimes a puzzle you've just finished is too good to dismantle, and after working so hard to complete it, it would be disheartening to have to dismantle it.There are two possibilities:Either you buy a special puzzle frame, which is often more expensive than the puzzle itself, or you glue the pieces permanently together.
