The chevron (aka: zig-zag) is a well-known pattern that has definitely maintained its popularity over the years. One of my favorite ways to incorporate this pattern into a space is to paint it on an accent wall. It can instantly add bold personality to any room. A larger scaled chevron makes more of a statement while a smaller scaled version of the pattern is a bit more subtle. I would suggest sticking with lighter colors to achieve a calmer look that won't completely overpower your space.
