drawing is symbol making reduce everything to geometric shapes and the fewest values value relationships are really important thumbnil to explore possibilities test: is design interesting and possible in two values large shapes make the design, about the wholistic effect you must alter reality, not just copy what you see to make good design, alter values to make readable and demonstrate focus find and emphasize rhythms reduce refine and interpret (can draw multiple times to get to this process)
