Bend the Rules In kid-friendly spaces, there’s no such thing as pattern overload. Combine stripes, polka dots, and prints with chenilles and cottons for a lighthearted look. Pick a two-tone palette, such as green and blue, and use several shades of each hue. Boost character in a beach bedroom with simple board walls. Mix up the look by placing some boards vertically and some horizontally, as though they were installed on a whim.
