Just when I was getting back to the blog, we rearranged furniture and disconnected the computer. but it was not for naught. :)
The living room/addition has been drywalled, taped, mudded, and painted - primer and two coats of white. While we were at it, I also re-painted the hall, most of the dining room, and painted the rest of the dining room for the first time - 3 coats over the paneling. So we are now gleaming white everywhere, and back to the new normal.
Bob also installed some light fixtures, but I don't know if they show up in the pictures.
