Don't you just love it when you do something and it actually LOOKS like you got something done. I got the first section of skin on and the first window mounted today. Only about 50 feet and 8 more windows to go. This is a lot of work, but, I think it looks a lot better than just filling in each window. Besides,  the way Bluebirds are put together, with that individual eyebrow above each window, there isn't really a good way to fasten the top of any individual panel short of kinda just gluing it in.  I was also able to get the bottom of the window high enough so that it will be above the kitchen counters.
