Bold, abstract artwork adds a touch of modern-chic over a bed or dresser. To create one for pennies, pick up a thrift store painting with a clean-lined frame. Cover the old artwork with a coat of primer, then brush on your own design using black and white paint, or a mix of colors that suits your room. The best part about this easy DIY? You don't need to be an artist to make it great—in fact, the more imperfect, the better!
