But the top of the doorway was still ugly! It was a sheet of plywood, with some moulding to make it look tidy. But that only reached as far as the old vertical plywood sheet. And it had also only been varnished there! So I needed to act. And I decided to rip off the moulding, make the edge smooth with filler, and paint over the entire thing. And I did! It wasn't too much work. So that eyesore is gone now too! Success!
The plywood and the moulding (held in place; I forgot to take a picture before I ripped it off)
You can see where the vertical plywood reached
Filler hides everything
Now it blends in with the walls!
