Shape

Shape and form are often used interchangeably.  In art how ever shape is more correctly used to refer to two dimensional outlines.  Shape identifies objects, can be regular and irregular, it creates patterns and shows movement and scale.

Shape is created by merging, touching and intersecting lines. It can also be defined by colour and tone and by texture. Everything has a silhouette shape as well as other internal shapes. The shapes that emerge between shapes are called negative shapes. Shapes can be regular or irregular, closed or open.
