This document discusses contour line drawing techniques. It explains that contour lines involve slowly tracing an object with your eyes while your pencil follows in the same movement on the paper. The key aspects are to move at a slow, continuous pace while coordinating your eye and hand movements without looking away from the object or down at the paper. It distinguishes contour drawing from outlining by noting contour involves capturing details within the outline through different line techniques like blind contour, modified contour, and cross contour lines.
