Lastly, the time-honored tradition of building one side over the other to assure they are symmetrical. In this case, the right side is put upside-down, then wax paper laid down, and I will start to make the left side to match. Maybe more tonight, or tomorrow.

As far as tools go, I have just been using an Xacto knife, french curves, straight edges, T-pins, sandpaper (60 grit and 220), nothing exotic.
