Here's a quick sketch I just threw together showing me drawing a sketch that I'm just throwing together.

The sad thing is, that's really how I draw. Right hand on the mouse drawing the lines in Flash. Left hand hovering over the
ctrl-z keys. I make a slight mis-movement,
ctrl-z, do it again. I can mess up a single line ten times in the course of twenty seconds and just keep undoing it, re-drawing it, undoing it, re-drawing it, undoing it, etc., etc. until it's right. It sounds monotonous, but it's actually a pretty slick process that appears to be helping me get better every time. At least, that's my opinion.
