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.
Gesture Drawing Exercises: When you begin investigating your subject matter in the initial phase of a high school Art programme, it can be helpful to make several first-hand gestural drawings. The best of these can be selected for your final portfolio (taking advantage of a photocopier or digital camera to reduce in size, if necessary). A small still life scene can be depicted just as easily as a large moving form.
This delicate cross contour drawing helps to communicate the bumpy surface of the shell. Note how the shell pieces that are furthest away from the viewer are thin and light, whereas those that are closest are darker and thicker. Note also how the direction of the contour lines relates to the shape of object that is drawn, with lines projecting outwards from the centre of the shell.
The illusion of three-dimensional form, space and distance can be conveyed in a contour drawing through the use of varied line-weight (darker lines in the foreground / paler lines in the distance) and perspective.
