To make a room feel layered and lived-in, combine jewel tones with varied textures like velvet pillows and linen drapery. Mix wood tones and metals across furniture and lighting, add antiques or vintage pieces, and use patterned rugs or wallpaper accents. Avoid matchy-matchy decor; instead, curate collected accents that tell stories. This creates warmth and personality, aligning with 2025 trends embracing comfort and character.
