No matter what I'm working on, or how busy I may be, I confess... I always find time to doodle in my sketchbook. There's nothing more freeing than letting your mind wander with a pencil or pen on paper, is there? I'm always interested in the types of sketchbooks other cartoonists and artists use, too... The type of paper dictates the types of media one can use, and all artists have their preferences, including style (hardbound, spiral, clipboard, etc), even the brand of the sketchbook. So, what kind do you use?
