1. Taped the left skirt in place and drew extension of the lines on the green tape down onto the skirt. This located the centerpoints of the holes to drill.
2. Took the skirt off and drilled most of the holes. (There are a few at the aft end of the skirt that I will have to re-mark because the green tape ended up being underneath the skirt.
3. Clecoed the left skirt back in place.
4. Began locating and marking the holes along the bottom edge of the skirt, using the duplicator strap.
