Looking for a unique boutonniere? It's easy to use skeleton keys wrapped in ribbon as boutonniers for the ushers and add another one to the hand wrapped bouquets carried by their female counterparts. The bride and groom would each have one wrapped in white or silver. A unique way to accent your wedding.
Another option is to have your florist attach the skeleton key to a more tradional boutonierre. Both ideas courtesy of The Bride's Cafe. In this link you'll find other ideas for ways to incorporate these vintage keys into your wedding day.
