When I was in first grade, I got in trouble with the law. And by the law, I mean my teacher, and by trouble I mean a note was sent home. This was a big deal to me. Not only did I consider my relationship with my teacher to be pretty darn special since we shared the same birthday and everything, but I never got in trouble. And I do mean never.
This particular trouble was over one of those paper fortune tellers. You might remember these things from your own grade-school days. The basic idea is that you fold your square sheet of paper into quarters, fold in the corners, flip it over, fold in the corners again, and - suddenly - you've got yourself a cool little game. Until you start adding in some elementary insults. Then there's trouble.
All that to say this: if you've ever folded one of those fortune tellers (whether or not yours contained the sort of insults that mine did), then you're well on your way to understanding how to make one of these beautiful little paper stars (I first saw these stars over here). Seriously, guys, they're so easy.
