Overdraperies may be used alone or with glass cur- tains, roller shades, or Venetian blinds. They should reach the floor, and ordinarily they should be made so rhat they can be drawn over the windows to exclude the blank night view. Casement Curtains. Sill- or apron-length draw curtains, often made of standard casement cloth or a plain medium-weight opaque material, usually function in place of shades or blinds to give privacy. They may be used alone or with draperies. See page 9. Glass Curtains. Sheer curtains hung next to the window may be used with or without draperies. Net, organdy, dotted Swiss, voile, Celanese, scrim, marquisette, rayon gauze, madras, lace, or ninon are used for this purpose. Glass curtains give daytime privacy, soften the light, and modify the harshness of the frame and shade. They may be hung at the ceiling line if the draperies are hung there. They should be exactly the right length, stop- ping at the window sill, bottom of the window frame, or 1 inch from the floor. They should be very full, well tailored, and per- fectly clean. Plain white, translucent material is desirable. Sheer ruffled curtains are effective without draperies, in some Early American or Colonial rooms. Roller Shades. Roller shades are practical, as they are easily adjusted to give privacy or to exclude light. Although there is structural unity in having all the shades at the same level, a shut-in feeling results from keeping them all halfway down the windows, as many women do. It is often advisable to keep them rolled up out of sight unless utility demands otherwise. As a rule, it is well to have roller shades light in color, preferably like the walls or woodwork. Roller shades are sometimes made by tacking oil- cloth, chintz, or other fabric to rollers.
