The upstairs bedroom walls are in, now making the room look like this:

As you can see, the ceiling is still unfinished, but the 2×4’s are in place to hold up either the 1/4″ drywall, 0.5″ drywall, or ship lap boards.
Although I’d prefer ship lap boards, they are about 4x more expensive than drywall, so once reinforcements have arrived,
we will see if the drywall stays up without sagging.
At least this room is now taking shape. It’s small but not too small.
