Herringbone is always a classic. You can add it to just about any room modern or traditional and it will work. Here are some of my favorite ways to use herringbone.
How about a more modern twist on an old favorite, spice it up with a bright colored herringbone fabric.
This rug from West Elm is neutral enough to go in most any space. The herringbone texture adds interest.
Or how about and incredibly awesome painted ceiling in a herringbone pattern. Done by the fabulous Mandi at Vintage Revivals. I die.
