This document discusses formal elements of line in art. It defines a line as showing a path between two points, and notes that lines can be curved, zig zagged, horizontal, or implied. The direction of lines can imply certain feelings - horizontal lines imply tranquility, vertical lines imply power, and diagonal lines imply movement. Lines that converge can imply depth or distance. The document also provides an overview of artist Keith Yahrling's background and style, noting that his work features repetition of lines and patterns to portray issues of abundance, waste, and consumerism.
