I wanted to put the rug right next to your fabric to see how it looks! :-) I like it! All of the rugs that I posted, except for the braided rug, came from www.selectrugs.com. You'll have to go in and use their search feature -- I was searching under floral rugs and traditional rugs in ivory/beige shades. (I have ordered from Select Rugs and have been very pleased with their service.)

The Thema Rug (first rug) you selected is a flat weave. I not sure about that fringe they've used on the rug. Looks like a different color and inexpensive. The 9x12 rug is $3,399 and that's a lot of money for that rug. I'm wondering if the cavernous size of your room could use a rug with a bit more thickness, and maybe even larger than the 9x12 size. Oh, I guess I assumed that you were getting a wood floor, but now I see that you are putting this rug on wall to wall carpet. Is the carpet a level loop, like a sisal would be? If you want to create a monochromatic room, that could be very attractive, as long as some of your finishes are dark to complement the beams. Sorry but I think it was a mistake to allow the hearth of the fireplace to wrap around the side of the fireplace and interfere with the window treatments. If we're dreaming here with no concern about $$, I would hire back the mason and cut back the side ledges even with the edge of the fireplace stone wall. If you don't do this first, you'll have to settle for drapery on only one side of the windows and I'm not sure you'll really be happy with that solution. Those windows look a bit dwarfed in comparison with the size of the room, so a recommended drapery treatment would make the windows appear larger in size. I would mount bronze or iron rods about a foot down from the beams and hang basketweave textured linen panels on either side of the windows, with woven wood roman shades to match the beam finish, mounted under the drapery panels to control the light and privacy..

Sort out the piano first. The way the lid opens now, you're throwing the sound against a hard surface, the wall, not out into the room. The pianist has their back to the room, and you have no softening elements like a rug under the instrument, drapes at the windows. I would move the loveseat into the bay window so the piano can be turned to get the most out of it. Here's a nice way to handle the drapes and sofa in the bay.

I deleted my posts due to no response. Also, I skimmed through your other post and I notice your Mom is 91. And, there is very little, to no indication of what your Mom would prefer here. I would encourage you to keep any new rug in the same colorway as your Mom’s present rug - with the warm brown tones PLUS REDS in the rug. Alternatively, maybe just get her present rug cleaned... It’s a nice rug. You can look into environmentally friendly ”green” type of cleaning services. And why not just let her keep her current wall art ? Art is really a very personal thing. If she loves the art - just leave it. It’s her space. To “lighten up” the space - and only if your Mom is open to the idea - maybe add a floor lamp.
