And there it is: white wall problem vanquished. The empty gold frame is a placeholder for a future painting. I swapped out the black curtains on the sliding door with red ones. And to top it off, there is still plenty of room to pull the leaves out on my little dining table and seat four people.
The difficult task of moving the desk and everything associated with it is done. I have a detailed plan for the wall that I'll work on tomorrow. Interestingly, this is where I wanted to put the desk when we first moved in, but I was vetoed.
