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 Or use outdated lanyards as the background.
NFS- for those asking about our board, here is how it was made:) we got shadow box display board, spray painted black, cut and added the cork board, cut and added colorful paper and added pins! We love it!
