                              SHAPE- Defined area of geometric or organic form.

                                DIRECTION- Horizontal, vertical, or oblique.

                                  SIZE- Relationship of the area occupied by one shape to that of the other.

                                  BALANCE- Similar to balance in physics.

                                  GRADATION- Size and direction produce linear perspective.

                                 REPETITION- With variation is interesting, without it can be monotonous.

                              CONTRAST- To compare to show differences.
