My son has a mirrored wall in his townhouse - with a vaulted ceiling. He has tried off and on for 2 years to get a contractor to remove the mirrors, but no one is interested (not even interested enough to give him a huge bid). He has considered ways to cover the mirrors, but hasn't come up with a good solution.

I'm anxious to see what you do! And yes, your view is lovely!

You could put fabric up.

moulding attached with glue/panel adhesive in an interesting pattern.

you can also add window film, like a frosted finish and fill in some of the panel spaced if you do an applied moulding.https://www.amazon.com/Texture-Privacy-Non-Adhesive-Bathroom-Decorative/dp/B0BJ8T3KYK/ref=asc_df_B0BJ8T3KYK/?tag=hyprod-20&linkCode=df0&hvadid=647240650999&hvpos=&hvnetw=g&hvrand=5833974040338394474&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9008504&hvtargid=pla-1960791509895&psc=1&mcid=06899831d58935dd9742931cfc2bea9f

Stick on wall mural?

I would do curtains off a track mounted to the ceiling.

Nothing can replace the sparkle that a mirrored wall provides to a room.

Geez don't do those cheesy arches.

Why isn't your sectional sofa in front of the mirrored wall?

You can apply molding to the face of the mirror to create a new vision.

Depending on the size and weight, you can hang artwork directly on the mirrors using either adhesive hooks or adhesive.

Beverly always comes up with the best ideas!

That would be why she has the most followers of any designer on Houzz I guess.

I think just rearranging the furniture wouild be where I would start as mentioned the sofa in front of the mirror and see how that works . I ahd visions of the tacky mirrotiles but yours is lovely.

How about window film?

Saw a designer show home in an historic district where fabulous vintage empty picture frames in all shapes and sizes were hung on a mirrored wall that draperies hung, floor to ceiling, on both sides. Me? I would leave the wall!!! Who wouldn’t want to see that view x2?
