Drawing is the oldest and simplest form of art. Drawing images can be used to express feelings, done for the enjoyment of the activity, or to share ideas with others. There are no boundaries on methods used to create your drawing so you are free to use the medium that suits you best. Using pencil, charcoal, ink or pastels, you can draw in line or tone or use both. Line drawings are made with lines only, while tone uses shading and differing degrees of light and dark.
