I found a neat resource for storing cans, the ones you buy at the grocery store, if you have a lil' money to spend. And I do mean a LITTLE. Nice, right?
If you don't have any money, but you have some cardboard, I think you could still make one. HERE is one example. You can find full directions HERE and the diagram HERE! ^_^ I'm hoping to try it out myself!
