For an easy way to add pattern to your walls, consider this rectangular mirror. Surrounded by a wood frame, it features a chevron pattern that meets itself on each side of the frame showcasing an X motif. Done in a palette of black and cream, the black stripes are added with an imperfect, almost painterly effect. Plus, the neutral hues let it blend in with almost any color palette. This accent looks great paired with a simple side table in an entryway or hung above a vanity in a half bath.
