Are you finished with your old puzzles and looking for new challenges? Then stop by the library and trade your jigsaw puzzles for ones that are new to you. You can swap one-for-one on the spot. Tables will be set up for puzzles of different sizes and types. Puzzles should be geared for adults and have no missing pieces. Bring a picture of it put together, if you have one, to show that it has all its pieces.
