Every year when we go on vacation, I collect stuff (Aaron helps) to put in our scrapbook along with all of our vacation photos. I collect things like ticket stubs, postcards and tourist brochures. Those things are generally flat and fairly easy to store. Eventually they get sorted out and glued onto scrapbook pages.
Generally, I am thrilled when my kids follow my example, but when it comes to collecting treasures, their stuff dampens my joy just a bit. It is usually the stuff that you find at the bottom of beach buckets: sand, rocks, and shells, and stuff you find along the trail: sticks and pine cones. The mere suggestion that these valuables be thrown away leads to pint-sized revolution. So, I had to come up with a way to display (read "contain") these mementos.
These glass canisters did the trick!
