This fabulous box pleat modified drum lampshade is sized for sofa and table lamps as well as floor lamps. We made this one with a pinking shear ruffle along the top and bottom. It measures 15 inch top diameter, 18 inch bottom diameter and 13 inch slant. The color is Azure blue habutae silk and has a brass washer spider. It requires a 10-10.5 inch harp.
