A relaxed approach to painting a Permaculture concept diagram. Created by April Sampson-Kelly of Permaculture Visions. * economical equipment - wet and dry watercolour pencils * putting in shade relative to the size of the object * why to keep the illustration rough and abstract to enable viewer participation and empower them to make informed adaptation as the design evolves * Use clarity only to show the aims of the plan. Avoid set placement of tools or devices. Keeping the plan abstract enables modification to achieve the goals. * Three of the main goals of this particular design are explained: solar access (sun trap), wheelchair accessibility of the garden, water harvesting systems * colour to indicate dryness and depth of saturation of moisture e.g. orange for dry and dark blue for wettest areas * April also refers to a quote from Bill Mollison that any permaculture design is better than none. * April mentions a useful textbook: The Permaculture Earthworks Handbook: How to Design and Build Swales, Dams, Ponds, and other Water Harvesting Systems by Douglas Barnes (chapters 1 and 7 are the most accessible and instructive for designers).
