Throughout the 1970s Sol LeWitt expanded his vocabulary to include broken lines, not-straight lines, lines drawn at random, arcs, circles, and lines demarcating basic geometric shapes. These shapes originally included circles, rectangles, and triangles, but soon extended to rectangles, trapezoids and parallelograms, which LeWitt considered to be secondary shapes. At the point that Wall Drawing 335 was conceived, the artist had begun to fill in the shapes with parallel lines.
LeWitt also adopted a new material around this time; he replaced the fine pencil lines of the early drawings with thicker markings created by crayon. In the mid-1970s LeWitt also began working with black, yellow, red, and blue backgrounds.
Wall Drawing 335 was originally executed in white chalk. The chalk proved to be extremely dusty, however, and LeWitt eventually switched to a water-soluble white crayon, like those used to create the drawing at MASS MoCA.
