Once your treasured tokens are secure, reassemble the frame or close the glass door on the front. Now, take a quick pause to admire your handiwork (it wasn’t so hard, was it?). Don’t give up now though. Instead of leaning your shadow box up against the wall, find a spot for it right away. All you need is a measuring tape, a pencil, a hammer, a nail, and a level. Use the measuring tape to find the right spot on the wall, mark it with your pencil, and then hammer away. Once your shadow box is hanging on the nail, don’t count on your eye to tell you if it’s straight—use the level to ensure it’s not tipping to one side or the other.
