oh by diy shirts I mean all the shirts that I have oil stains on or paint... that I wear when I just don't give a f or hwne I know I'm going to get more dirty. I have one that is an old mozzila appu shirt... with a sweet gtradient on it. The gradient came from me usinga circular slot cutter on a mill that tossed metal and oil at my midline and taperd off as it fell.
