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.

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.

Blind Contour Drawing : A blind contour drawing contains lines that are drawn without ever looking at the piece of paper. This forces you to study a scene closely, observing every shape and edge with your eyes, as your hand mimics these on paper. The aim is not to produce a realistic artwork, but rather to strengthen the connection between eyes, hand and brain: a reminder that, when drawing, you must first learn to see.

Pop artist Andy Warhol is famous for his brightly coloured silkscreen artworks; however he was also a rampant drawer – often filling sketchbooks. He won many prizes for the drawings he produced in high school. The illustrations shown above – comprising of slightly smudged and blotchy black lines – have Warhol’s typical off-beat style. They were completed using a basic printmaking technique: pressing sheets of paper into a wet ink drawing, transferring the image to the second sheet.
