Blind Drawing Exercises: Blind drawing is an excellent way to start a high school Fine Art programme. Drawing wobbly lines that bear little resemblance to the chosen object is relaxing and stress-free. Often, a classroom bubbles with laughter at the unexpected results. Blind drawing stretches the arms and soul; eases you into observational drawing without fear.

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.

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.

Cross Contour Drawing Exercises: This is an excellent way to gain familiarity with the volumes and three-dimensional forms in your project, producing analytical cross contour drawings that are suitable for sketchbooks or early preparatory sheets.
