A big thanks to Wes for providing some inspiration and dimensions. This thread on another site provided quite a bit of inspiration.
It just so happens that I had some small offcuts just the right size for a mini guitar. So, I broke out some poster board and a couple of large plates and started drawing circles.
The body measures 10" wide by 14 3/8" long, I'll be going with a 16" scale and single pickup. On my neck "template" I drew out measurements for 15", 16", 17", 18", 19", and 20" (obscured by the body "template" here). I thought 16" was a nice compromise between in-scale and playability. I've got enough scrap to do 2 more, so depending on how this one turns out I may try another in a different scale. We'll see.
Ribbon Sapele leftovers for the back.
African Mahogany for the neck.
Some leftover curly maple, just wide enough (not bookmatched).
