At sketchbook club, we drew a shiny, black, plastic boot that had lots of reflections. This is for Sketchbook School homework which was a lesson given by Jane Lafazio: draw lightly in pencil, go over in pen, frame it up and add watercolors. Lucky I'm working in a small notebook--this type of sketching takes hours.
But, I still prefer the blind sketch. Nothing like fast and furious to get interesting lines!
