Caution: Some art geekery follows.
A spread from my pocket sketchbook. I've been drawing frames and coming up with ways to fill them, without any preliminary pencil lines. I've also attempted to make my pen and ink lines more sketchy. I simply take a trusty Pilot V5 and attack the paper. I realize using a V5 isn't exactly the most artsy way of doing things. I should use my sketching pens or my fountain pen. But I don't. My Pilot is cheaper, I like the way it feels, and I don't have to worry about losing it or having it explode in my pocket. (Yes, I've had fountain pens do that to me. Don't ask why I ever thought to put a fountain pen in my pocket.)
