This is perhaps my avorite way to draw. I don't know where I got the idea from, probably just from messing around in some boring meeting one day. I try to use a single line and let the pen wander over the paper, trying not to lift the pen and worry about stuff like line quality and all that. I think I do my best work when I use this kind of doodling method. It's also relaxing and very fun. Quite freeing indeed.
