I might start designing some guitar body shapes that are based on the Golden Ratio, and I was wondering what tools would be essential in creating a multitude of applications for the ratio, such as drawing Golden Rectangles, triangles, spirals, etc.

Also, where can I get paper that would be the full size of a guitar, but not too expensive? And should I just use normal pencils and rulers, or a special type? I'll obviously be going over the final product in some kind of sharpie or pen, but I'd like to know if professional designers use a specific type of pencil or ruler for accuracy.

Also, any other tips would be appreciated.

Soda sucks.
Newsprint would probably be cheap. Check out an art supply store.

if you pull this build off dude you are basically required by holy law to paint it in the theme of Tool's Lateralus!
