Planar Analysis Drawing Activity: This can be a great introductory drawing exercise, especially if you are moving towards Cubism or abstracting scenes into geometric form. Wire can be cut and bent into shapes with pliers to create three-dimensional ‘drawings’, often resulting in a work filled with flowing, curved lines. These wire sculptures can be attached to a two-dimensional frame or a flat surface, hung in the air, or be left free-standing, changing in appearance as a viewer moves around the room. Due to their flexible nature, wire sculptures often move slightly in the wind, adding an extra interactive element to the work.

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.

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.
