You need to show adjoining spaces. Please add 2-3 more photos.

A tapestry may be a nice idea with the height of your ceilings, leather furniture and rustic type table.

I would hang art above it. The piece can be as wide as 75% of the table's width. I tend to decorate below the window and door frames, even with higher walls. If you do the job right at "people level" the upper portions will fade out of site.

I love the long tapestry suggestion. You could add a wall sconce on either side of it to show off the tapestry's beauty.

Don't load a big table on a big wall with a bunch of teeny objects. Less is more.

Sandra, you would put hardwired sconces over a movable piece of furniture? So if she ever wants to change her arrangement, she's stuck with sconces in an odd place on a wall? Candle sconces, maybe, though I'm not a fan.

Can you put in built in storage space.

Is that a doorway next to table. I don't think you want your art extending above the top of doorway.

Wallpaper! Don't turn your nose up at the thought of it, it's not your mom's wallpaper anymore. There are incredible choices out there, large graphics, metallics, beads, grass cloth and murals. Take advantage of those tall ceilings and increase the visual space of the room.

What room is this in and what is the piece of furniture used for??
