The goal is to create an illustrated guide for anyone interested in using drawing as a tool for thinking and communication. In its purest form, freehand drawing is the classic sketch without the aid of mechanical means. Therefore, emphasis is placed on freehand drawing with simple tools as the most direct and intuitive way to express our visual thoughts and sensations.

Just like writing, the ability for freehand drawing is acquired and developed through practice. This does not require innate talent or expensive tools, but rather time, patience, perseverance, and a willingness to practice. More important is to understand how sensory vision and visual thinking collaborate in the creative process of drawing.
