The document discusses the 9 principles of design: repetition, emphasis, pattern, proportion, movement, balance, variety, and unity. Repetition and pattern create unity within a work of art by repeating elements. Emphasis uses contrast to draw the viewer's eye to a particular area. Proportion ensures all parts of a work relate well. Movement guides the eye along lines and colors. Balance distributes visual weight evenly. Variety engages the viewer with different elements. Unity creates harmony between all parts for completeness.
