Make your neutral living room feel complete by adding four key finishing touches: a right-size oversized area rug, layered ambient lighting, varied heights and shapes in furnishings, and personal color cues. Begin with a rug that unifies your seating, then layer multiple light sources like dimmable floor and table lamps for warmth. Arrange furniture pieces with height variation, such as combining low sofas with tall plants or sculptural tables. Finally, introduce subtle colors through art or accessories that reflect your personal story. These intentional steps transform a serene room into a welcoming, finished living space.
