What I did for sketchfest (instead of sleeping) http://www.ellenmilliongraphics.com/sketchfest/sketchfestart.php?id=6353
4B and 7B pencils on 65 lb Canson sketch paper. Paper is about 5.5" x 8.5 but the drawing doesn't fill it, more 5.5" x 5.5" roughly. I expect I'll upload copies elsewhere and make prints of one kind or another (possibly of a digitally-cleaned-up version…). These two amuse me.
