How do I choose an 8x10 area rug for a living room I am redoing when I like monochromatic and contemporary but tend to get a little boring. I chose a gray sofa and 2 blue/gray chairs with an oversized walnut colored leather ottoman. Will post pics when it arrives in a month. I like the shag look because it adds textural interest but have 3 kids and two cocker spaniels so need to be practical too. Any suggestions on pattern or material?
