Cross Contour Drawing Exercises: This is an excellent way to gain familiarity with the volumes and three-dimensional forms in your project, producing analytical cross contour drawings that are suitable for sketchbooks or early preparatory sheets.
The illusion of three-dimensional form, space and distance can be conveyed in a contour drawing through the use of varied line-weight (darker lines in the foreground / paler lines in the distance) and perspective.
The angle that these techniques are applied may remain constant within a drawing, or it may change in response to the angle and direction of the forms. For example, cross-hatching may flow around the surface of an object in a similar direction as cross contour lines. These techniques are also a great way to create the illusion of texture (see our article about observational drawings).
Pop artist Andy Warhol is famous for his brightly coloured silkscreen artworks; however he was also a rampant drawer – often filling sketchbooks. He won many prizes for the drawings he produced in high school. The illustrations shown above – comprising of slightly smudged and blotchy black lines – have Warhol’s typical off-beat style. They were completed using a basic printmaking technique: pressing sheets of paper into a wet ink drawing, transferring the image to the second sheet.
