11am-noon, Avalon Free Public Library, avalonfreelibrary.org

Drop off your gently used jigsaw puzzles at the library from May 1 to 8 to receive a ticket for the number of puzzles you drop off, with a limit of 10. All puzzles must be in the original box and have all their pieces. On May 9, stop by the library to exchange your ticket for the same number of new-to-you puzzles. Drop-in puzzle swaps are welcome on the day of the exchange.
