Bare walls have plenty of advantages—ample surface area for finger painting, an absence of disapproving Churchill posters, and no mirrors reminding you that your hair is on fire. Fill rooms' middles with furnishings so you can keep walls clear with today’s Groupon: for $15, you get $30 worth of art, accessories, and furnishings at Souk Home Decor.

Drawing on designs from around the globe, Souk Home Decor's gallery-style showroom displays accessories, mirrors, lighting, and vases that accent and enliven homes and offices. A 10-inch Moroccan lamp ($12.50) and an array of candles lend a touch of luminescence to living spaces, and delicate blown-glass hearts cast amber reflections across sun-stricken coffee tables ($24). Pick up a Talavera piggy bank to brighten up shelves or end tables until you've saved enough for a real pig ($12), or hang up a monogrammed pillow for fully upright naps ($19.95 each). Souk Home Decor hosts an art exhibition the first Saturday of each month, and guests can browse the latest pieces while perusing home-decorating wares.
