That is actually something I've done before. For the life of me, I can't remember what I did it with, probably a pen or lighter. I know it was small and dark colored. Or maybe it was one of my erasers, though, they're all white. Well, I know I've done that before. Whenever I can't find something, and I have a big cloth in my pocket, I make sure to unfold it to check.
