It then lists the 3 key steps as: 1) preparing materials like pencils and sketchbooks, 2) choosing a subject and viewpoint, and 3) drawing the outline and adding details like shadows. The document encourages readers to try sketching instead of thinking it is too difficult without attempting it first.
