Here's a fun idea. My husband is a runner/adventure man. He accumulated a stack of numbers and bands from finished races that were just sitting on a shelf collecting dust (on top of the dried mud). I had a large shadow box that I bought from Hobby Lobby so I decopauged it with a map of Wisconsin ... Where we live and where he races.... Then just put the mementos in it closed it up and hung it. Now whenever he finishes a race we just open up the back and add more! This idea would work for any kind of collection! If you have a memory box let me see them! Share yours in the comments!
