My world is a 3×5 index card. Every design, illustration, and thought has started from a doodle on a index card. I keep a stack of them besides the computer at all times. Once a month I have to go through them and discard the ones that do not make any sense anymore. And that is a lot of them!
All hail the 3×5 index card! May your lifestyle of lined on one side and blank on the other forever be rejoiced!
