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.

A gesture drawing is completed quickly – often in short timed durations, such as 20, 30, 60 or 90 seconds – using fast, expressive lines. Gesture drawings capture basic forms and proportions – the emotion and essence of a subject – without focusing on detail. Due to their rapid completion, they are a great way to record movement and action, as well as increase your drawing speed, confidence and intuitive mark-making skill. Gesture drawings are best completed with smooth, easily applied mediums (chunky graphite pencils, charcoal sticks, pastels, soft brushes dipped in Indian ink, for example), without the use of an eraser. They are often completed on large, inexpensive sheets of paper, where you can move your arm fluidly, be bold with mark-making, and not worry about mistakes. As with blind drawings, gesture drawing is an ideal warm-up activity.

A cross contour drawing contains parallel lines that run across the surface of an object (or radiate from a central point), such as those that appear on a topographical map or a digital wireframe. The lines can run at any appropriate angle (sometimes at multiple angles) and may continue across objects and into the background. Cross contour drawings typically follow the rules of perspective, with lines drawn closer together in the distance and further apart in the foreground. In this type of drawing, the illusion of three-dimensional volume is created entirely with line.
