I've always envied people who are actually gifted draftspeople -- people who lay down the exact right line on the first try, and whose drawings are paragons of minimalism. R. Crumb, for example -- there's a video showing him drawing with a pen and never laying down a bad line. Whenever I watch that video, I have an envy meltdown.
My point? With a tablet and stencil, by being able to delete things, I could pretend to have actual drawing talent. :)
