Abstract: A curtain cover attachment for vertical blinds has flexible sheet material portions that fold over opposite sides of each vane of the blinds from a front edge thereof, the panel portions extending also between the vanes. The cover is supported by first tabs that fold over one end (the tops ) of the vanes opposite respective supportive stem portions thereof from the front edges, the tabs being secured by hook-loop fasteners that are hidden between the cover and the vanes. Additional tabs and associated fasteners can also be used between the stem portions and the front edges of the vanes, as well as at opposite ends of the vanes.
