This document discusses various design elements including line, shape/form, space, texture, and color. It describes the effects that different types of lines like vertical, horizontal, and diagonal have on a space. Vertical lines suggest strength while horizontal lines create a sense of rest. Diagonal lines break up monotony but can disrupt structure if overused. Curved lines suggest grace and motion but may create restlessness if overused. The document also discusses how shape/form, space, texture and color can be manipulated within design to achieve different feelings and appearances.
