In this ink drawing, a small grid experimenting with different line techniques has been included in the top left of the work. Some of these have been selected to apply tone to the work, carefully replicating reflection and shadow. This image was completed using a sharpened bamboo stick dipped in black ink.In this sketchbook page Samantha imitates and analyses a line drawing by Vincent van Gogh, discussing the suitability and appropriateness of each technique. Note that when learning from artists, it is rarely necessary to slavishly copy an entire work; replicating small pieces (as in this example) is often all that is needed.

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.

A cross contour drawing contains parallel lines that run across the surface of an object (or radiate from a central point), such as those that appear on a topographical map or a digital wireframe. The lines can run at any appropriate angle (sometimes at multiple angles) and may continue across objects and into the background. Cross contour drawings typically follow the rules of perspective, with lines drawn closer together in the distance and further apart in the foreground. In this type of drawing, the illusion of three-dimensional volume is created entirely with line.

This article contains exercises for Art students who wish to produce contour line drawings, cross contour drawings, blind drawings and other types of line drawings. It is a teaching aid for high school Art students and includes classroom activities, a free downloadable PDF worksheet and inspirational artist drawings.
