The study of plant details required in botanical illustration will open your eyes to nature's beauty and develop your understanding of botany. This course begins with drawing: learn form, perspective, lighting, and texture.

Using various techniques, create drawings with contrast, balance, layering, and design.  Develop your artistic eye using a small range of graphite pencils. Following the same layering technique you will learn in pencil drawing, move into watercolor. See how colors interact with each other in hue and value and how to select the right colors to blend, best representing your subject.  Advanced students work on the artistic study of a living plant, from graphite to watercolor.  Demonstrations will be given along with attention to individual needs.
