Thanks for the feedback everyone. I am recovering this week fron an injury and bored, bored, bored, bored, bored! It is SPRING outside which makes it worse! Because I can't do much, I thought I would at least try to make myself useful on Garden Web. :) Az- Your piece over the mantle was actually resized from something I found online. I know Hobby Lobby and Garden Ridge get tons of stuff every year. Also try garden centers. I couldn't find an online source because I guess that shipping for something that large and heavy is prohibitive. The windows were pieces from an iron shop online that I scaled to fit your window. Those were almost 15", but they have different designs in different sizes. They have a 200 page book of iron that is great fun to look at (but their web navigation is less than stellar) --- I think you are right about a lighter table. I love that your furniture is so grounded, but a little lightness would be great. Something like that one in Daisy's living might be nice. OH! I love those mirrors Johnatemp posted! I have copper on the brain right now. I have been searching for months for the perfect vintage copper tray to go under my dog dishes. (Yes, you read that right:)

My techy brother is visiting me. He says that you could mount a screen on the wall opposite the patio doors (get a motorized one with a remote) and then mount a projector over the patio doors. The screen is only visible when you are watching something, if you paint or otherwise cover up the casing, and you can build a box to camoflage the projector. It may sound wacky, but he has a projector and screen mounted to the ceiling in his family room and you really don't notice them when they're not in use. If you don't want to go that route, could you get one of those TV lift cabinets where the TV is hidden inside and then rises up when you need it? That could go under the small window. Even if the cabinet blocked the bottom few inches of the window, it might look nicer than having the TV block the window. Other than that, it does look as if the corner where the TV is now or the wall where the mirror is are your best bets. If you floated some furniture in a L-shaped configuration, either two sofas or a sectional, you could take advantage of the views and the TV screen.

I vote for keeping the pine as an accent wall. While looking at the comments on your pine wall, an ad came up for Ted's Vintage Art Prints - https://tedsvintageart.com/ . I think two or three of these ( maybe 24"x36") would look good on your wall. You could frame them or mount them on foam core. I would take out the fluorescent lights and add interesting floor lamps. Get a bigger stylish clock and hang a little lower.

https://www.houzz.com/products/query/drum-side-table/nqrwns Here are lots of drum side tables. The rug should be big enough to slip under the front 1/3 - 1/2 of the sectional and extend past the right and left ends of it by a foot or more. Use blue painter's tape on the floor to tape that out, then measure and buy a rug in the closest size to what your taped rug measures.
