My thesis is based around the golden ratio and Fibonacci ratio. I am making 89" (7'5") vessels. Four of them. They will have welded bands at certain inch measurements. Those measurements are where the Fibonacci ratio comes into play. One of the vessels is going to be very precise, a cone and created with the strictest of guidelines. The other three will be based around variations of that. Still using the math but allowing me to work very freely with the form.
