Inverted box pleat draperies - Drapery panels made with an inverted box pleat are double the fullness of the window. So they always look full and luxurious. When you close these drapes, the top of the panel is smooth and flat (creating a clean modern look). Then, when they're open? The box pleats stack PERFECTLY. They never look fussy, or "old lady"... I love this tailored style.
