Ball point on coupons + photoshop. some time ago I thought i'd find more times to draw. So I drew on used coupons in the car while waiting at a long red light or for a passenger to arrive. Most of the time, I had to draw within a minute and then quickly throw the pen aside before the light turned green again. Not the most convenient or safest way to draw (unless you are a passenger). But this is what came out of it.
