Sketching is the use of sketching pencils, charcoal or other products to draw objects, pictures, landscapes, people and anything else. Sketching is normally done quickly, as a type of doodling, with the final sketch not intended to be a finished artwork. It is very popular as a form of observational art, and is very portable due to just needing some sketching tools, and a sketchbook or pad.
