This 5-step drawing assignment begins with blind contour drawing of a partner to learn observation skills. Students then sculpt the 2D drawing in wire to interpret the lines in 3D, extruding them into deep volumes. Next, they draw the 3D sculpture to demonstrate how lines flow in space. Another drawing is made of the previous one using new cross-contour lines that travel the head form. Finally, students draw a head from observation applying geometry and cross-contour lines.
