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 It may not be published online or shared or distributed in any other way, as per our terms and conditions.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 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.

Continuous Line Drawing Exercises: This drawing method is great for sketchbooks and drawing from life. It can be an excellent starter activity, with drawings completed on large, inexpensive paper that can be scanned / edited / cropped and used in other ways within your projects.

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.
