(Paraphrased from Art: Images and Ideas by Laura H. Chapman)
Almost every artist has been inspired by nature-land, sky, plants and animals. Artists have always marveled at the forms and structures that make up nature’s designs. The guides created by Arthur Wesley Dow included a list of principles of design. They are also guides for understanding how a work is planned.
The following is a list of the "Principles of Design":
Rhythm, Movement
Balance
Proportion
Emphasis
Pattern
Unity and Variety
