I need a way that is easy enough to do but accurate enough so that I don't get the bottom half of the mat getting out of sync with the top.
I figured using a template of sorts would be way better than measuring each hex individually.
Step 1: I printed out my template using Publisher to make sure each of the hexes was the right size and so on. I then laminated the paper so that the template wouldn't get soggy and tear. Also not the guide lines to help line the holes up with the existing marks.
Step 2: Then I took it into the shed and drilled holes into each of the corners.
It's going to take a while to get them all done. Definatley going to be a job that requires headphones and some good music. A long album too, maybe The Clash's Sandinista! or better yet Helloween's Keeper of The Seven Keys Parts I through III. Better be on the safe side and queue them all up.
