As I get older I find myself thinking about stories more and more before I work so that by the time I eventually sit down to write them, I know more or less how it's going to look, start or feel. Once I do actually set pencil to paper, though, everything changes and I end up erasing, redrawing and rewriting more than I keep. Once a picture is on the page I think of about ten things that never would have occurred to me otherwise. Then when I think of the strip at other odd times during the day, it's a completely different thing than it was before I started.
