Window Treatments
As the term indicates, window treatments can be more than mere window coverings. Treating windows is thought of as "packaging" them as a design element rather than simply covering them for function. Coverings are used to protect privacy, insulate heat and cold, and filter light; and while many people consider window treatments more aesthetic, they too can be functional. Although window treatments are technically more decorative, this term has evolved, and is frequently used to describe most types of window coverings. Sheers, drapes, curtains, cornices, blinds, shutters, and valances are all examples of standard window treatments. More than one type can be incorporated into the design plan, through the use of layered treatments, and this type of arrangement can include both style and function. For example, if you select light filtering blinds as window treatments (for obvious reasons), you may also want to install a valance or window topper to soften the lines or to add color. Alternatively, you might layer more than one aesthetic treatment to create a dramatic effect: Consider the use of floor length curtains along with a cornice. Some designs incorporate several layers of window treatments, such as a room-darkening shade to filter light at certain times of day, with sheers to let light in at other times. Topping this arrangement might be drapes made from luxurious fabric.
Swags and Jabots - The most formal, traditional, and elegant windows are often draped with swags and jabots at the top of the window. A single swag might be draped across the top of a shorter window, or multiple swags might be draped across the top of a longer window or a group of windows. The soft, gathered swoops of the swag might be accentuated with passementerie (gimp, cord, beads, fringe or braid), or crowned at each point along the top with fabric rosettes or another detail. The jabots, which are the tails that cascade down on each side, frame the window with S-shaped or zigzag folds. Often, the jabots are lined with contrasting fabric, or are edged with passementerie for greater emphasis.
Valences - Valences are the soft fabric treatments at the top of a window. Valances serve the practical purpose of concealing the mechanical hardware on the window treatments. Valances can extend the height of a window, filling the awkward space below the ceiling and above the window. The height of the valances should be in proportion with the window height and the ceiling height. A good guideline is to start with a standard valance height of 14 inches, and to adjust the proportions from there. If the window is wide, making the valences larger will make the ceiling look lower. If the room is long and narrow, making the valences wider than the windows, so that the curtains pull all the way back to the window jambs, will make the room look wider.
Cornices - Like valances, cornices conceal the drapery hardware, and provide a decorative element at the top of windows that gives them a more finished appearance. While valances are soft, essentially a short curtain, cornices are hard. Cornices are usually made from wood that is painted or covered with fabric, or from fabric that is stiffened with buckram. Buckram is a coarse cotton that has been stiffened with glue or sizing. Cornices are usually rectangular, although they might also have a shaped edge, which adds a more architectural element.
Lambrequins - Like cornices, lambrequins are often made from a firm board covered with fabric. In addition to a shaped edge, lambrequins have "tails" that extend partway down the sides of the window.
Pleats - There are many types of pleats, so depending on the style, the effect can be either formal or casual. Essentially, the pleats add fullness to the drapery panels. A good guideline is for the total width of the fabric to be 2 1/2 to 3 times greater than the width of the area to be covered.
