Continuous Line Drawing Exercises: This drawing method is great for sketchbooks and drawing from life. It can be an excellent starter activity, with drawings completed on large, inexpensive paper that can be scanned / edited / cropped and used in other ways within your projects.

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.

A continuous line drawing is produced without ever lifting the drawing instrument from the page. This means that, in addition to outlines and internal shapes, the pencil must move back and forth across the surface of the paper, with lines doubling back on each other, so that the drawing is one free-flowing, unbroken line. To avoid the temptation to erase lines, it can be helpful to complete a continuous line drawing with an ink pen, varying the line weight, as needed, to indicate perspective and areas of light and shadow. Like the drawing methods described above, this drawing method develops confidence and drawing speed, and encourages your eyes and hand and brain to work together. Continuous line drawings work best with in-depth observation of your subject, without interference from your thinking mind.

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).
