I repurposed some vintage jewelry pieces, mainly brooches and earrings, into some unique cabinet hardware for my daughters' bathroom. Threaded posts and epoxy from the hardware store made it a pretty simple project. http://threescoopsoflove.blogspot.com/2012/07/vintage-jewelry-cabinet-hardware.html
