I bought a canvas whose dimensions conformed to the “Golden Ratio” whose dimensions conform to the Fibonacci sequence and what has been used by many artists over the years. Apparently, the length x width ratio is subconsciously pleasing, and having read "The DaVinci Code", I thought it would be interesting to try out this shape. The ratio of the canvas is based on the "Divine Proportion" (also known as Phi), and the aspect is 1.62:1.
