I love this idea from Martha Stewart! Vacation Memory Jars are an easy way to store all the treasures the kids pick up on vacation. In one jar you can put that pine cone, rock, shell, magnet, postcard, photo or any other things your kids collect along the way. This project works for any kind of vacation. You can make a beach, forest, mountain, historic or big city jar. These jars are easy to find at places like Wal-Mart, Hobby Lobby or JoAnn’s.
