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.

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).

This wire drawing exercise ‘using line to create space’ is completed by students within a 3D Art class, working over photographic portraits. Having a base image to work from (this could also be an earlier observational drawing) makes the process of transferring from two-dimensional to three-dimensional much easier.

A contour drawing shows the outlines, shapes and edges of a scene, but omits fine detail, surface texture, colour and tone (‘contour’ is French for ‘outline’). According to Wikipedia: 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.
