There's a pretty good one by Delgondahntelius (sp?), I think.

The biggest secret to hand drafting I know is to use tracing vellum, also known as onion skin. You can pick up a roll of it at any art supply store for a few bucks. Make your initial drawing however you like, then lay the vellum over it and trace over the lines you want to keep. Use a new piece for each new level of detail you add. From there, I like to just scan all the layers of vellum into the computer and create the final image there. It's also possible to use carbon paper to transfer the drawing to illustration board, or you can leave your final work on vellum and simply mount that to something.
