How do you wear buttons at competitions?

[KaitlynL]

As build season comes to a close, all I can think about is competitions. This year (and the next two after that), I will be attempting to collect more buttons than one of my team's alumni, who is now a mentor. Anyways, I really need a cool, creative idea for wearing my buttons at competitions. I thought of a cape, but that would probably end up being too heavy once I accumulated a large amount of buttons. So, how do you guys wear buttons, and what do you think I should try?
