and since "There are no pictures on the wall"...

how about some art to liven things up?

Welcome to the forum! I think you'll enjoy the people here; they're so talented and have so many good ideas. I'm a relative newcomer myself.

For some reason the first thing that came to my mind was Audubon prints. I can really visualize them in your setting. Other ideas would be botanical prints, or prints of American primitive art, especially those that feature children, cats and dogs. I frankly can't envision any room without art and this will add character to your space without bulkiness. Early American furniture also looks marvelous with Oriental rugs, traditionally those with red or dark blue backgrounds. Try to go for a large enough rug so that the chairs will still be on them when they're pulled back.

Photographs of your space would be a big help. I'm especially curious about your wall color and window treatments.
