11. Excessive Themed Decor

Over-committing to a single motif—such as nautical, farmhouse, or retro—can make your living room feel more like a themed attraction than a comfortable, timeless haven. Designers caution that heavy theming often dates quickly and can overpower the space. Instead, they recommend weaving in subtle references to your chosen style through color, textiles, or a few select accessories, allowing for personality without sacrificing balance. This approach keeps your decor fresh and adaptable. For inspiration on how to achieve a harmonious look with just the right amount of theme, check out Apartment Therapy’s guide to balanced theming.
