A function of the Golden Mean (Each successive number is the sum of the preceding two numbers.) Proportioning for projects like a chest of drawers or a set of shelves. HAMBRIDGE PROGRESSION (i.e. calculating graduated drawer heights) 1. Make square A • A (A = drawer width) 2. Strike arc from square A • A's diagonal 3.

Final height of the drawers is a function of the number of drawers and drawer width.
