Pretty Room. I think you have enough decor. I would spend the money on a rug and window treatments. Look for art (not decor stuff) for over the sofa that speaks to you. Don't be in a hurry. Try local artists. Minted.com also has lovely pieces. I think you need larger and higher end tables.

Nice mockup from Celery. I agree with jck regarding not rushing. Art over a sofa should be about 2/3 to 3/4 the sofa’s length…and not hung too high as shown in Celery’s example. Maybe 4-6 inches between sofa and art so they have a connection.

Thank you so much

I looked at your saved photos, and does this one show direction for your room? for curtains, etc...?

I'm copying this from houzz.com: "If you have a wall of windows that almost stretch end to end, add lightweight panels between them to create an illusion that there is no break between each window. This is a great look when using non-functional (stationary) drapes because functional drapes could require more widths of fabric, which gets costly, and you end up with a bulkier look that will allow in less light. If you need privacy for this look, use a shade mounted behind the drapes. Hang the rod longer than where the windows end to create the look of wall-to-wall windows."

Nice room. Just a little FYI here you might do if you want.

It is possible to spray paint the curtain rods, and I have done that myself. Wouldn't be hard to spray them black to give you some contrast with white curtains.

The look of stationary panels that frame the windows is beautiful. Are the blinds needed? They are such dust collectors and really bring the look of an elegant room down. An unobstructed view through to the sun room framed in black possibly with grids would be fabulous. The drapery rods as is, leave an uncomfortable gap between them and the window moldings. I would have to lower them. Painting them black would be fab if you aren't painting the window molding black too. I would want some sort of a soft vining black design in the curtains. Solid white is too stark and sterile.

Here’s a rug idea. https://www.rugsusa.com/rugsusa/rugs/rugs-usa-freya-abstract-eclipse/Gray/200ECRK29A-P.html

And maybe just pick up your wall color for the drapes. What color are your walls, exactly ? On my screen it looks like a sage (?)

Also, do you have children in the space? If so, please rethink the glass table.

Here’s the rug:

Below visual is not exactly true to actual rug colors and texture - but the rough idea:

ETA:

Art is a very personal thing. Etsy.com is one good resource, for all types of art. The art does not have to match the space. But thinking in terms of your color scheme, I pulled up a few posters, just for fun.

Can picture casual grey/soft white throw, if it's like the chair's colors-

Rather large, but casual stonewashed type fabric... and might complement wall color, and wood

A lumbar for center of sofa, but I don't think this is ideal with wall color - what is name of the wall paint?

Thank you for all your advice, so appreciate. The previous owner did not leave any paint and said she can’t remember the exact color but it’s a light green. Hope that helps.

Ottoman in center of room could be good spot for color - and color that you check goes well with your wall paint.

The Linden curtains at penney's could be a subtle black/white... did you check I hope?

Perhaps consider painting walls white.  I also like the idea of bringing some lighter wood tone for the coffee table too.  As for a rug, perhaps a more textural off white...  Inspo below
