Part of the challenge is to make it "look" like a telecaster. Well to me, the easiest and fastest way to make a body that looks like a telecaster is to trace an existing Tele. So I did just that on a large piece of cardboard:

Now that would be all I need if this was a one-neck instrument. However, the sympathetic strings will have their own neck, so the body has to be increased to allow for the second neck. I made some quick calculations, moved the tele over by the needed amount, and traced it again. Then I connected the two images, and smoothed the lines, drawing the finished outline darker with a Sharpie.

Next step, cut it out & transfer this to the wood.
