Contour drawing is an art technique in which the artist sketches the style of the subject by drawing lines that result in a drawing that is essentially an outline (the French word contour meaning "outline").[1] The purpose of contour drawing is to emphasize the mass and volume of the subject rather than the detail; the focus is on the outlined shape of the subject and not the minor details. However, because contour can convey a three-dimensional perspective, length and width as well as thickness and depth are important; not all contours exist along the outlines of a subject.[2] This technique is manifested in different styles and practiced in drawing development and learning.
