DECORATIVE hem options
The classic look found at the bottom of the roller shade is called a plain hem; the fabric covered bottom rail is the bottom of the shade.
In addition to plain hems, decorative hem styles are available for all fabrics except screens.
Hem styles extend the fabric below the bottom rod of the shade. The scalloped bottom is 6" to 8" below the bottom rod; the length measurement you give to us is the "bottom" of the scallop. Please be aware that decorative hems, particularly styles like Florence and Chalet, can leave light gaps between the sill and the trim even when the shade is lowered fully.
