We love puzzles yet I do not love losing pieces and finding larger storage options for them. A good friend gave me the following tip:
Cut out the picture of each puzzle from the top and sides of the box. Assign each puzzle a number and write the number on the back of each of the pieces (so you know where that lone puzzle piece goes that you find 2 weeks later). Store everything together in a slide-zipper top plastic food storage bag, labeled with the name and number on the puzzle.
We were able to fit all of our puzzles in a small plastic bin, ordered from 1 to 25. :)
