1. Taped the lower edge of the canopy with painter's tape, then drew two locating lines per frame hole. This will help locate the existing holes when it comes time to drill the skirt. 2. Used a silver marker to make dots on the lower tube and all three ribs of the canopy frame at 2" intervals (1.5" on the ribs). 3. Drilled #40 holes at these locations. (Nearly finished the left side before calling it a day.)
