Hex nut "brass rat" bracelets

For Campus Preview Weekend, I was in charge of coming up with a craft for the visiting students, and I found a cool craft where you make hex nut bracelets or necklaces.  They're a nice nod to MIT's brass rat, and pretty straightforward to make.

And believe if or not, there were so many people there that we almost ran out of supplies!  It's interesting holding dorm events, because even if you've been doing it for six years, you have no idea what events will be popular and which won't.

So many people!
