Claim Text:
1. A covering for an architectural opening comprising in combination: a headrail; a shade material suspended from the headrail for movement between extended and retracted positions; and a manually operable stiffened pull cord operatively connected to the shade material and movable upwardly and downwardly to move the shade material between the extended and retracted positions, the stiffened pull cord having an at least partially rigid core and an outer sheath at least partially surrounding the core, wherein: the core does not move relative to the sheath such that the core and the sheath move together during the upward and downward movement of the stiffened pull cord to move the shade material between the extended and retracted positions; the core extends substantially the entire length of the stiffened pull cord; and the core is flexible but somewhat rigid so that it resists becoming entangled with itself.
