My first two sketches today were done with the dot-to-line contour approach using an HB woodless graphite pencil. After I drew them in I looked for the terminator lines and added shading. On the third sketch, I toned the paper with the graphite, erased the light area on top of the lid, and shaded the rest of the form without drawing contour lines first. I like the effect of no hard contour lines in this one.
