Gesture Drawing Exercises: When you begin investigating your subject matter in the initial phase of a high school Art programme, it can be helpful to make several first-hand gestural drawings. The best of these can be selected for your final portfolio (taking advantage of a photocopier or digital camera to reduce in size, if necessary). A small still life scene can be depicted just as easily as a large moving form.

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.

This delicate cross contour drawing helps to communicate the bumpy surface of the shell. Note how the shell pieces that are furthest away from the viewer are thin and light, whereas those that are closest are darker and thicker. Note also how the direction of the contour lines relates to the shape of object that is drawn, with lines projecting outwards from the centre of the shell.

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.
