Show the third wheel some love with this three part necklace charm set. You and your lover get the red heart to show the world the undying affection you have for each other. The third wheel gets the large tire charm with "third wheel" thoughtfully engraved onto the sidewall. Give as a gift or as a not so subtle message for the "wheel" to ponder on. I can make a fourth, fifth wheel etc. although if you're having that sort of multi-wheel-friend issue you are beyond the help of a simple charm necklace.
How to put together: Each of the lovers stand on either side of the person assigned as the "third wheel"; then connect the hearts through the middle of the wheel charm. This might prove awkward... This is a work in progress.
