Upcycle a thrifted mirror or ornate frame as a display for trading pins! I think it would be cool to have a black one like this with haunted mansion wallpaper fabric in the background. Or use outdated lanyards as the background.
This pin is of the Tokyo Disney Haunted Mansion. It features Jack and Sally holding hands in front of the gates to the Haunted Mansion in the background. It is pin on pin with a yellow banner at the bottom that reads Haunted Mansion Tokyo Disneyland.
