I agree. The options are almost endless. But for some reason, I see a houndstooth pattern. Maybe it's because I'm eyeing a navy houndstooth rug for my living room. :) Your sofa reminds me of dark, rich libraries. But you could so easily go with something lighter, like in yaya's picture. Find pictures you like and start from there.
