At the very least? Paint the adjoining walls as the wainscoting.

I DO realize you love the paper, but the repeat .....it just makes it not the best choice for an accent wall. It wants to wrap a room, it's not the best for a stand alone, and for the most part? A stand alone wall is rarely necessary.

I'd probably break the mythical rule......add a big round mirror AFTER I paint the other two walls wainscot color. and look for some art, for those. Related...., simple and bright on a dark wall

The space looks lovely! Given the height of the sconces and their distance, it might be difficult to find the right piece for good balance and importantly, doesn’t overtake the beautiful wallpaper you love. Therefore suggest a modern sculptural piece and don’t hang as high as the sconses. Piece below is 40x40 and if interested, cut out Kraft paper and test placement to see if size/shape suit, which might also help with a decision on other things you are considering.

Love the simplicity of something like these, placed randomly.

This is one side of a living floor? Can we pictures of the rest? That would provide more context, more help: )

I would include framed art, in gold.

I would also paint the adjacent walls the color of the paper background.

Lower the light fixture to 30-36 inches off the table.

Agree with Jan's comment about painting the walls the same color as the wainscot. And also, to continue the wainscot on the right wall. Dark and moody dining rooms really make a statement.

It's not wainscot, it's a banquette.

Depending on how the dining space relates to the adjacent living room, painting the side walls may not be a reasonable option - though I agree, if it was a stand-alone room, dark walls would be fabulous.

You don't need anything on the wall with wallpaper. To style the table, I think a runner, with a bowl or candles works pretty well. But a runner with a piece of driftwood works, too. Or just a cluster of candles. Or you can highlight a collection of something you have: china figurines, glass animals, ginger jars, etc.

Search Houzz for DR pics to see lots of options.

I'm sure Sabrina Alfin Interiors would agree.

There was probably an inspo photo to the idea for the paper.

But. when you see an inspiring to you picture? You have to adapt it to your situation. You have to ask, how can I make this thing I love, work in MY space? DOES It work in my space: ) ? Would the idea be better in another area of my home, and sometimes that will happen.

Why? Because nothing lives in isolation. It lives in a context- the stuff, the rooms around it. Just one more reason to add picture of all the surrounding areas.

@Sigrid generally I might agree with you about not needing art work, but the way the sconces are hung, the space is just begging for something to go in between.

Looks like those side walls are vaulted and connect/open to other spaces ... so they probably don't want them painted dark.

A pair of sconces, that far apart? Fairly BEG to fill the visual void created.

In reverse? Putting a focal point on the wall, whether mirror or art ?Does NOT beg for sconces.

Funny how it works and doesn't work: )

"Looks like those side walls are vaulted and connect/open to other spaces ... so they probably don't want them painted dark."

If they are vaulted and connected.....that could be the inspo taken out of context of the total space. We'll never know without pics of the rest: )

Thankyou everyone for your thoughts. Here are some e recent pics of the other side of the room. The ceiling in the middle of the room is 17’ and it comes down to about 9 1/2 on the sides. I chose the dark wallpaper to lend some weight to that side of the room since the other side of this open space is a stone fire place. It’s been a gradual process to finish this room The feature is really the view of the lake (can’t see in this pic)

The added photos are going to be very helpful. They add context as to why the wall paper was only added on one wall instead of wrapping the corners in order to continue the paper on the adjoining walls.

The photos are also a good illustration of Jan's comment above - will an inspiration photo (or idea) work in my home? This paper may have been beautiful in an inspiration photo that the OP saw - but my guess is that it was not shown on one wall at the end of a large open concept space - that has 9.5' high ceilings on both ends of the room - and vault up to a height of 17' in the middle.

This is paper would have been great in a powder room - where it could have been used on all four walls in the room = a dramatic effect.

AHHHHHH I might have gone bolder in scale. and a mural. There a zillions.....

For muted and a nod to the fire?

Yes I understand the deep color, and you loved that paper. Not sure it does what you wanted...

Even something with more of the surrounding wall color and yes,,,,,a bolder scale and view.

Hi Sue F!

I have a few minutes and caught this before heading out — hope to come back later — but if not — gorgeous paper!

Oh dear, what am i reading above? Powder room paper? Powder room paper has much more negative space (less dense pattern for smaller spaces). Your paper choice and location — all of this is done correctly. My goodness!

Please leave paint as-is, and try to avoid mirrors — mirrors outside the bedroom or bath is French Provincial and meant for narrow entryways in a garcionnaires to make them appear larger, something American colonials imitated after trips abroad. Mirrors sprang up everywhere in the American home. Aiiigh!!! No no no!

Also, please, ! NO mod or abstract shaped wall art over that gorgeous pattern!

Very lovely addition! Perhaps a carved frame with arch echoes of the main window? Light in color/finish, with a little gilt to match your accessories, add gold detail on the cream cushions and done! Have shopping fun! ❤️!

A mural does not DEMAND a powder room, any more than a dining room demands a toilet: ) Good grief..........lol

You might consider painting the all the walls the same dark blue as the banquette. It would be very dramatic and beautiful.

Holy cow! Context is everything! Everything I thought of for solutions was all wrong when I saw those huge windows with a view of the lake and the rest of the very nicely styled room. Very nice space!
I know you love the wallpaper, but it's not fitting in with the rest of the room. It's the wrong scale and style. In that large open space, that wall would benefit from being painted the same color as the side walls, the banquette, or one of the other colors in your decor. If you already have one large piece of art for the space between the sconces and it's appropriate for that entire room, hang it there. Otherwise get a right-sized mirror for now. Anyone facing that wall at a dinner party would enjoy also being able to see the lake view reflected through it. Art would have to be better than the lake view to make it worth replacing the mirror. The sconces and chandelier appear to be too high in the photo, but measure the height and see. An electrician could adjust the sconces. You might want a different chandelier there if you can't lower it. I love the light though, so I hope you can lower it or use it elsewhere.

Styling the table when not in use? Some version of a bowl of fruit (or decorative balls), arrangement of flowers (fresh or dried or artificial or even feathers), or candelabra comes to mind. How about candelabra-like piece you hang porcelain hummingbirds from. It should be something you like. What do you like? What do you have? Do you have any collectables you could display? Think about where you will put the item when you need to use the table as a table.

Wow Thankyou for your thoughts and suggestions. I’ll take the. I to account

Beautiful room. I might just lower the chandelier. No artwork. I do love the idea of extending the dark paint around the room.

I think the wallpaper doesn’t do the room justice. The light murals that Jan posted are far more cohesive with your high ceilings, neutral walls and stone fireplace. It’s a big job, but I would take that wallpaper down. If you can envision one of the last two murals from Jan, you’ll see that they work really well with your entire open space.

It’s a beautiful house.

Love your room!!! I like the mirrors that Architectural Digest posted. Could you maybe lower the chandelier some? It’s seems a little high.

@Sue F I think you'll get more helpful ideas if you edit your original post to include the pictures of the rest of your room. It would also help to include a daytime photo showing the view out the window. If the view is drop-dead gorgeous, a mural could pale in comparison.

You have lovely taste and just trust your instincts. Maybe hold off adding anything on that wall and once you accessorize the table, the area will feel more finished (can always add down the road). Suggest some lovely clay pieces (spread out a bit and include height), which will complement both the dining area and the entire room, which is important to consider also.

No matter what? The "balance answer" was not in the navy background, or the scale of that paper.
