I just took a sheet of 3M vinyl, an art school chopper, and started chopping squares. I made stacks of 2.75 in squares. On the rudder, I used the verticals stab as my straight line. I started out trying to be extremely careful with drawing pencil lines and making sure that the squares went on right on the pencil lines, but after some experimenting, they actually went on better without the pencil lines. As I said before, they don't "give" at all. So once you had 3 or 4 down, lining them up was easy. Corner touching corner... Repeat. There are a couple sections that weren't perfect, but with the nature of that type of pattern you cannot see it easily. Even I cannot see them easily, and I'm my own worst critic.
I tried not to wrap the vinyl around the corners too much, because with the thicker stuff I bought it would be building in a week point for wind to get under. I also tried to only touch the squares in the middle where the stickyness would be as critical if it were slightly compromised.
