For sometime now, I have been saving all my hotel room keys, thinking that eventually I will use them for some sort of art piece to commemorate all my travels. Some of them are beautiful, pretty art pieces, others plain, but together I feel sure they will be useful. Well, today a friend sent me a link to a site using them to make jewelry.
