A few weeks ago, I picked up a ceramic cow's head for four bucks at Goodwill. It's admittedly a strange piece, but I couldn't leave it behind. (Just look at those sad yellow eyes.) It's now mounted on my bathroom wall, where it serves as the perfect necklace hanger.
Therein lies the secret: Shop for eccentric pieces that don't just take up space (especially if you live in a small apartment). That way, your quirky accessories look less like grandma's freaky clown figurines, and more like artful, organic design elements.
