Roman blinds are made from fabric that is designed to pleat when raised. The blinds are constructed by mounting slats, which are connected to cords, into the back of a fabric panel. When the blind is lifted, the cords pull the slats together and force the blind to fold into pleats.
Roman shades are a type of window covering used to block out the sun. Roman shades are different from standard window shades in that they stack up evenly when being opened; however, when they are open they are visibly smooth, not bumpy or ribbed like typical vertical shades or blinds.
