Ha! ME TOO! My biochemistry/biology/anatomy/physiology brain is sooooo straight-laced! I have to do something to loosen it up! Don't worry, the geometry will come so naturally to you. You'll intuitively understand how to shape a two-dimentional object to fit a three-dimentional body. Or, a mathematical stitch pattern might really work for you! (Try to design one based on a prime number, or pi, for example.)
Us left brainers will figure out our own way to venture into right-brain territory.
