Painted stripes and stenciled patterns are easy to create and fun to customize, and they can bring a lot of depth and character to the room.
Simple designs can have big impact. Try a repeating pattern of geometric shapes such as polka dots, wavy lines or diamonds.
Play with color: use different colors or tones from the room's palette to add interest to a repeating pattern. If your wall color is strong, apply silhouetted shapes in white for a bold contrast.
Use a stenciled pattern to draw attention to a piece of furniture or architectural feature, or to highlight a piece of art. Try stenciling a scrolled frame around a favorite photograph or group of photographs, or a mirror. Create a colorful floral garland around a window molding.
For a more temporary wall accent, try using vinyl decals, which can easily be switched out when the season or your child's style changes.
