This document provides examples and guidance on using contour line drawing techniques. It discusses how contour drawing uses varied line thickness instead of shading to define shape and form. Several masterworks are shown that demonstrate effective use of thick and thin lines to depict shadows, surfaces, and details. The document emphasizes using harder or softer pencils and pressure to vary line darkness. It also stresses the importance of strong composition, such as following the rule of thirds, in contour line drawings.
