Estes Saturn V Wraps Tip

In the Saturn V instructions you are told to extend two pencil lines up the body tube at the raised tunnel locations. These lines are used to align and position the upper wraps.
You are directed to draw two lines, one on each side at the base of the tunnels. It's a little hard to get the two lines right at the sides of the tunnel on the vacu-form wrap.

I took an easier way out.
TIP: One single line, centered directly on and above the lowest raised tunnel. A pencil line was marked at the centers of the tunnels on the upper wraps.
A single line - easier centering and alignment.
