You've worn one. Or you've bought one for someone to wear. We know what they are, but spelling it is the problem: boutonnière
As such, I'll refer to it as "the b word" from here on out.
I was inspired by a trip to Swede's Fly Shop. Tobe and I visited a few weeks ago, and I couldn't get all those lovely feathers out of my head. The base is a black cardboard star, which is completely obscured by all the stuff on top. In addition to the feathers, I've added a metal pocket watch and a couple buttons. Finally, I personalized it with each grooms person's name. Look at all those M's! There's also one here for Tobe and his father.
