I ran my needle and laced with the wing flat. All hole locations were marked ahead of time. The light from the ceiling allowed me to see where the needle was when I was pushing it through from the top to go through the lower surface fabric, and I could see the needle point pushing against the fabric when I pushed it up from below. At the end, I was doing a rib in 23 minutes, and that was with 2 1/2” spacing on every rib. I need to get the left wing ready to go as soon as I can so I don’t have to relearn my skills.
