After I got the transit patch pulled off, I took the recliners over while I had a big hole to work with. It's much easier to move furniture that way.
Then I finished up the window frame part of the wall and set it to the side while I swapped the furniture around. The recliners are going in the girls place while the sofa was headed here. It turns out that it won't fit through the dooway going into the living room, so we'll have to do something different for our living room.
The new wall fit nicely in the hole and is well secured.
So I added the window and some house wrap to seal it up (sort of). After voting tomorrow, I am going to get the siding up and seal it in for real.
