If your board is over 8'
long and you need to make a two-sided 'spin' or 'flip' template, you
simply draw the nose half of the board on one side of the template, and the
tail half of the board on the other side. Just make sure that you mark stringer points on both ends and top/bottom of the template to mark the
point where you will place the template down on the stringer when you trace
your outline on the surfboard blank.
