Window treatments bring the pretty. In spaces outside the work core, such as breakfast nooks, none are better at this task than floor-length curtain panels, which offer big doses of color and pattern when they flank a large bay window or set of sliding doors. On a smaller scale, a swag of floral chintz draped over a single window can also make a bright statement. Roman and roller shades reveal texture and pattern when they are lowered, and stationary valances and cornices are like accent marks over windows you want to draw attention to. For the most decorative effect, choose fabrics that have eye-catching hues and designs, and have fun with trims, tassels, fringe, or bold banding to give the treatment a finished look.
