Focus: Line is the most basic element of art — a moving point that the eye follows across a surface.
- A line is a mark with length and direction: straight, curved, angular, or freeform.
- Lines vary in quality — thick or thin, smooth or rough, continuous or broken, dark or light.
- Contour lines trace the edges of a form; gesture lines quickly capture movement and energy.
- Implied lines are suggested, not drawn — by a row of objects, a pointing arm, or a gaze.
- Direction carries feeling: horizontal reads as calm, vertical as strength, diagonal as action.
- Artists use line to build shape, shade value (hatching, cross-hatching), imply texture, and lead the eye.
