I need to get plants for the pots.

As far as the orchids go... ice cubes once a week does the trick.

A piece of art has a life and IMO always works better than a mirror over a fireplace.

What a pretty and elegant room! I agree with art — black and white like your other pictures or something very modern/colorful (abstract, for instance). I’m someone who appreciates a soothing, monochromatic scheme, so I’d repeat the square shape.

A large mirror or a statement piece of framed art would be lovely - A large clock can also look lovely over a mantel. :)

Yes...art over the fp would be best. Pretty room!

Please no clocks in any space except bedroom and not even in a kitchen where every where you look there is a clock.

Love your space! I agree with the suggestions to for monochromatic art. Looks like you have black and white photographs above your couch. If it were my space I would look for either some black and white art or a black and white photograph similarly framed above the fireplace. Something rectangular to slightly fill the space but not so massive it overwhelms. I like the scale of the art above the sofa where there's some room to breathe and you can still see the lovely paint color.

I wouldn't go with black and white above the fireplace, but something with very subtle tones, probably an abstract, where you might also have a warm color to go with the drapes. I know that sounds a little soulless, to consider the tones in a room, but it doesn't have to be if you choose something you love. For myself a I would choose an unframed oil to give the wondefulr texture and originality of the real thing. I've found e-bay to be a great source of original art in all price ranges. You have a beautiful room that I can admire even though my style is much more colorful and traditional. You might try hanging the photos over the couch next to each other. If that looks too skimpy, perhaps two more over them would complete the look. A nice chair at right angles to the couch on the side away from the window might give a more welcoming and comfortable look.

I love clocks. Have one in every room, an artistic one over the fireplace. Not all of them are accurate lol! Different strokes for different folks. I like the big ones since my eyesight is going, but I do also think they are overdone a bit at this point.

Definitely art - and an opportunity to add some color to the room. It doesn't have to be vivid & bright, but can be softly colorful and the room would still look soothing!

Agree with mjconti...how about a little color to show your personality?

Love those blinds btw. Did you make them?

It is very elegant room, so something elegant above the mantel.

Choose any wall art to reflect your personal interest.

Because your mantel is high, consider something more horizontal rather than square -- keep the top of any art placed above the well below the top of the windows.

A good clock is always worth considering for above a mantel.
