Lines and Contours

Lines and Contours

Line:a one-dimensional element with no breadth or thickness, and therefore does not exist in the physical world.

Yet as lines dominate our perception of the visual world, they are essential in

representation in a drawing.

The Power of Lines

A line has inherent qualities of width, density, texture, pressure, continuity and rhythm

You will gradually develop sentiment with the lines coming out from your hand.

Your lines form the basis of your own drawing style

Contour Drawing

Also known as outline drawingDrawing with contour lines can enhance

accuracy by preventing us from messing through shapes with hatches and shades

The slow process of contour drawing forces us to see with clarity and accuracy

We are compelled to appreciate the nature, structure and geometry of forms
