So, while I was waiting my turn at the cable company today to sort something out, I reached into my bag for my sketchbook and realized I had left it at home on my desk. Darn! Plan B - I found my car insurance envelope and used the back of it to satisfy my sudden impulse to draw. Later, while I was making some phone calls, I tried to recapture my semi-manticore (less the human face) in my pocket moleskin. Moral of this story... be sure to keep your sketchbook handy at all times.
