How To: Draw A Perfect Freehand Circle

Need to draw some perfect circles? What is this, Venn Diagram class? Well I’m in the middle of sad and alone if it is. This is a video from DanHax detailing a technique to draw more perfect circles than you would have if you were just going to freeball it yourself without this pivot and paper-turning technique. Alternatively, trace a mug or plate. Do not trace your hand though, this isn’t Thanksgiving and we’re not painting finger turkeys.
