I found a large piece of cardboard laying around several months ago. It wasn't too big; just enough to be a little partition but still larger than a notecard, roughly around the size of a piece of paper. Given its sturdiness, I decided to make a (rather supersized) badge out of it. The design was kinda random, and done on whim. Save for the name writing (which is barely visible), I'm kinda satisfied with the end result.
