Christen Carter has been making buttons for bands, artists, and whoever else needs a good button since 1995. Her first customer, picked up while she was learning the trade abroad in England, was indie band Guided by Voices, and she’s just gotten bigger from there. Her company, Busy Beaver Button Company, now makes millions of buttons for clients like Missy Elliot, Bumble and Bumble, Threadless, Adidas, and Burger King. Not content with simply producing quality buttons, Carter has also become a serious collector of vintage buttons, and recently launched an online button museum to show off some of her amazing finds.
