Pattern

Pattern is an underlying structure that organizes surfaces or structures in a consistent, regular manner. Pattern can be described as a repeating unit of shape or form, but it can also be thought of as the "skeleton" that organizes the parts of a composition. Repetition focuses on the same object being repeated; patterns are made up from different components which are then repeated in the same way throughout the design. A seamless pattern is one that flows throughout without flaw in the beginning or end: the entire pattern is a single, coherent unit.
