In a first embodiment, a selective adjustment cord is provided as a very thin cord is extended through a series of thin engagement apertures which lie adjacent the main lift cord openings in a horizontal blind set. A series of engagement structures themselves cannot fit through the thin engagement apertures, and the selective adjustment cord is capable of movement of a louver having an engagement structure by only about the distance between adjacent louvers. In a second embodiment a slip fitting can be placed on specified louvers such that the first amount of upward travel of the lift cord will immediately lift the slats to which the slip fitting is engaged. Further movement of the lift cord will overcome the resistance of the slip fitting and allow the blinds to be lifted normally.
