Contour Drawing Exercises: Using line alone eliminates the challenge of applying tone, colour and mediums; and instead focuses attention solely upon shape and proportion. After completing warm-up activities such as blind and gesture drawings, slower, more formal contour drawings can be an excellent way to begin more realistic representations of your subject matter. Used intermittently throughout projects, contour drawings can also be helpful for the student who needs to work faster.
Line Techniques Worksheet: The worksheet below has been provided by the Student Art Guide for classroom use only and may be issued freely to students (credited to studentartguide.com), as well as shared via the social media buttons at the bottom of this page. It may not be published online or shared or distributed in any other way, as per our terms and conditions. The full size printable worksheet is available by clicking the PDF link below. This worksheet is suitable for middle school students, or senior students who have not had prior experience with line techniques.This worksheet introduces a range of line drawing techniques and encourages students to invent their own (such as using the first letter of their name). It allows students to practise using these techniques and to apply tone to a range of simple geometric objects.
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.
