Window boxes are great for dressing up the outside of your home, but they can also be used on the inside for decoration. For instance, the bathroom is a perfect place to use a window box as a stylish and functional shelf. Try a small window box in the mudroom for compartmentalized storage and hooks to hang coats. Window boxes can also be converted into elegant display cases with just a little wallpaper and a small puck light. With just a little imagination, the possibilities are endless.
