Update. After getting some advice from Fredo6 I went back to the drawing board on this. I stared at the wall for a few hours thinking before I came up with a technique to take any sphere or ellipsoid cut it into panels and easily unfold it (shown below). I'm unfolding everything now and will lay it all out to make a sewing pattern. Thanks gang. [image: IhEO_SP32-20100909-163213.jpg]
