Not sure what to showcase on shelves? First, consider what you love. Your interests and hobbies should come through in your accessory choices, says Debbie Wiener, an interior designer in Silver Spring, Md., who helps homeowners create spaces reflective of their everyday lives. "Kids' framed artwork, books, decorative plates, baseball cards or boomerang collections. Your home should look like you," Debbie says. Take stock of vacation mementos, crafts and items you're drawn to time and again when assembling accessories for a shelf arrangement. Design by Emily Henderson.
