Line is the foundation of all drawing. It is the first and most versatile of the visual elements of art. Line in an artwork can be used in many different ways. It can be used to suggest shape, pattern, form, structure, growth, depth, distance, rhythm, movement and a range of emotions. We have a psychological response to different types of lines: Curved lines suggest comfort and ease, Horizontal lines suggest distance and calm, Vertical lines suggest height and strength, and Jagged lines suggest turmoil and anxiety.
