LINE Lines draw our eyes from one part of an artwork to another. Their purpose is to define and call attention to areas the artist wants to accentuate. Verticals are alert and strong. Diagonals are active. Curves suggest rhythm and flow.
Texture adds interest and variety.
Some artists may add additional materials to the basic surface - feathers, string, straw, wood, for example. Simulated texture is a way of describing the appearance of a surface. It can be plain, uniform or varied. The artist uses lines, light and dark areas and color hues to make an object look either flat or solid, near or far in space, while working on a flat surface. Perspective, the illusion of deep space, is often created with the use of lines.
