A well-placed decorative mirror makes a small room feel larger and bounces light into dark corners. Round and irregular shapes read as modern; frames in warm metals add a touch of luxury.
Swap harsh overhead bulbs for warmer tones, and layer in a lamp for evenings. Soft textiles — a throw, a set of napkins, cushion covers — change the mood without a renovation.
Buy a few pieces from the same store owner when you can; their curated sets tend to share a palette, so the room comes together instead of feeling random.
