Most famous for his post-impressionist paintings, Vincent van Gogh also produced over a thousand drawings. In this pen and pencil line drawing, ‘Cottages With a Woman Working in the Foreground’, we see the stylistic swirling of line in the trees and clouds that is so characteristic of his well-known paintings. Capturing the swirling of the trees and the movement of the clouds, van Gogh represents the light falling across the textured landscape with quick, confident mark-making.

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.

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.

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.
