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.

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.

Line Techniques Worksheet: The worksheet below has been provided by the Student Art Guide for classroom use only and may be issued freely to students (credited to studentartguide.com), as well as shared via the social media buttons at the bottom of this page. It may not be published online or shared or distributed in any other way, as per our terms and conditions. The full size printable worksheet is available by clicking the PDF link below. This worksheet is suitable for middle school students, or senior students who have not had prior experience with line techniques.This worksheet introduces a range of line drawing techniques and encourages students to invent their own (such as using the first letter of their name). It allows students to practise using these techniques and to apply tone to a range of simple geometric objects.

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.
