Over a sofa, the print or group should run about two-thirds the width of the couch, so 24x36 alone or three 16x20s in a row. Over a mantel, one piece slightly narrower than the mantel. The common mistake is a print that floats.
What should go above the couch?
Something you can look at every evening without tiring of it: a wide landscape, a big sky, a horse at rest, a set of three that shares a color. Save the jokes for the kitchen and the bathroom.
Can I mix styles in one living room?
Yes, if one color repeats. Pull a color out of the rug and choose prints that carry it; a bluebonnet, a cowgirl and a city print will hang together if all three have the same blue.
