Two-way traverse rod.
Projected Window
To permit ease when opening or closing the window, the fixture should extend a little beyond the window on either side. Use a simple fixture, an oval or round rod, and a draw type of drapery. If drapery is to be shirred on the rod, take measurement from top of rod to lower edge of window. To length measurement, add 2½″ for a 1½″ hem which forms the casing and heading, and 2¾″ to 2½″ bottom hem. If sew-on or clip-on rings are used, measure from lower circle of ring to edge of window. To this measurement, add depth of top and bottom hem.
Awning Window
The type of drapery determines points of measurement. With tier type draperies, one for each section of the window, the measurements are taken from top to bottom of each section. Draperies hung from the top extending to lower edge of window or floor are measured from top of fixture for length desired. Tier type or cafe sections should be long enough to overlap the heading of the section below. Follow same procedure for measuring as for projected window. These draperies should be full—1½ times the width for medium weight fabrics, such as Chintz, Glosheen, etc., to three times the width when using sheer fabrics.
