I started out by modifying an image so it would work out as a template. That image was opened in excel and printed out. I included the file incase you need it. I arranged the printout how I wanted it, taped them together and cut them out with a razor blade.
Next I Traced the stencil I made onto a piece of MDF. I then used a scroll saw to cut out the stencil. Finally I sanded out any chatter marks within the template.
