Bower trained as an architect and taught architectural drawing, and this is the tips volume — a hundred and one short entries you can flip to standing on a corner. Materials, then the ones people actually need: How to find eye level and why everything depends on it, how to check an angle with a pencil held at arm’s length, how to size a doorway to a person, how to fix a drawing already going wrong, when to stop. Each tip gets a page or a spread with her own sketches showing the right and wrong version. Perspective is the spine of it, taught by a person who knows it cold. My favorite of the series.
