This door is not a pre-hung door, so it's way beyond my capabilities. David to the rescue. That man is a wizard with doors. He can custom make any door and hang it so that it's perfect. I admire that talent. It's something I'll never acquire in my lifetime.
If you noticed, there are now corner shelves beside the door. Before leaving to go care for my mother today I mentioned to David that I thought corner shelves would be a nice effect, since otherwise that corner would be wasted space. I returned to find completed shelves ready for use. What a nifty surprise.
