I remember seeing an article some time ago about a mom that put the puzzles in bags to reduce the space they took up and I decided to give it a try.
I had a small crate in the garage that fit quart sized zip lock bags perfectly! I think it was from the Dollar Store.
I had about 8 - 25 piece puzzles that I wanted to "de-box".
I cut the top of the box off - the part with the picture. Then I placed that and the puzzle pieces in the bag.
In the end I have a nice little crate that fits nicely on the shelf. Now when we want to play with the puzzles I can just grab the crate!
I liked the results so much that I did the same thing with several 100 piece puzzles that I also had in the garage!
