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).
When we first picked up a pen or pencil and started making marks on paper, we began with line. Whether self-taught, through trial and error, or guided by others, we learned how line defines form, creates structure, divides a frame, traces contour, creates tonal variation (cross-hatching, for example) and leads the eye from one part of a work to another. Initially a mechanism for getting outlines onto paper – identifying edges – we begin to applaud lines for their own merit: celebrate their presence…whether a quiet flick of charcoal on paper or a streak of graphite.
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 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.
