The flower bouquet repeats colors in the painting. Hide the wall panel with silver paper. Then place your plant in front of the windows. At the windows use bamboo blinds. Wood shutters lend a cottagey look to double windows.
Shutters open flat against the wall at either side of the window and fill the center space between.
Choose soft white curtains of ninon, nylon, or thin muslin for the lower sashes. Glass shelves across a mirror panel show off Sunday-best crystal. Dramatize the windows, even more with valance lighting. Hang the valance six inches from the window. Install fluorescent tubes two inches behind the valance.
