After addressing the idea of cross-contours, we covered technique of continuous line drawing. Continuous line drawings establish a path of the artist's eye. Once the artist puts the pencil to paper, the drawing is executed in one, long, unbroken line until the subject has been fully drawn. Start on any edge, establishing the largest shapes first moving towards the smaller shapes. Wrap the form in lines, crossing and establishing interior contours as well as the outside edges of the form. Your drawing should reveal the structure of your subject. For a more volumetric image, try to swell the line. In other words, have thicker and thinner areas of line quality. Remember dark lines advance while light lines recede.
