I don't wear a lot of brooches myself--I think I have only three and two I made myself--but seeing the sweet, creative handmade and vintage ones people wear has inspired me to start a collection. As the sort of dork who has Christmas socks, I find it a fun way to be festive.
I bought this brooch of Etsy a few years ago when I was doing a big presentation at my job having to do with food. It seemed like an appropriate good luck charm. Of course, I keep wearing it because I'm a foodie and I'm always hungry.
