‘Blocking’ just means blocking out how the action gets laid out on the page. In this case I was trying to work out the way Peckinpaw tripped and fell by making the gesture and movement read well in the limited amount of space of the 13″ x 4″ strip. Some artists call this the storyboarding stage.
It’s real important to do this before you start drawing the real strip or else you will be erasing and restarting a lot. I always try to avoid a lot of erasing because it can introduce smudges that are hard to get rid of. It can also mess up the surface of the paper making it harder to ink.
