Today I stood at my easel and began my sketch using the viewfinder. But I must have tilted it or something because the sketch of this paper lunch bag was too short. I could have caught this sooner by doing some follow through lines and plumb lines instead of jumping ahead to the interior details. And I rushed myself, so my shading lines are messy and inconsistent.

I might try again tomorrow, adjusting my block-in process and concentrating on getting the shapes right before worrying about shading. It would also help to study the bag for a minute or two to get a good sense of the different shapes in the subject (both in shadow and not) to give me a better sense of a path for sketching. Put another way: see the shapes, not the bag.
