Drawing has often been seen as a subordinate art form — that is, something you do before you make real art. Whether it's sketching a still life to learn about dimentionality and value, or drafting a cathedral blueprint, the speed and ease of drawing makes it an incredible learning tool. The art of drawing though, can absolutely stand on it's own. It's a stripped down means to visual expression. Line weight and texture means that any mark made clearly expresses the hand that made it, whether it's a pencil on paper on marks in the sand. Is it a tentative, delicate drawing? A rough sketch? The confident line of a master draftsman? Drawing is one of the oldest art practices, and it is also perhaps its most naked.
