Matching exact tones, textures and styles is one of the greatest challenges in interior decorating. Obsessively examining every wood grain or period detail and comparing shades of white does not guarantee perfect coordination; rather than risk ending up with the uncanny valley of living rooms, consider exercising some eclecticism, and mix various furniture styles. We recommend establishing a common denominator, such as colour, to be echoed throughout various pieces and gathered as a visual cohort. For the more experienced, grouping objects through their design eras can result in more complex harmonies. When done well, mixing styles can create an interesting room without it becoming overwhelming.
