Abstract

A window covering product has a headrail, a first rail substantially parallel to the headrail, and a first set of lift cords attached to the first rail passing through and out of the headrail, A second rail is substantially parallel to the headrail and to the first rail. A second set of lift cords is attached to the second rail and passes through and out of the headrail. A first tassel is attached the first set of lift cords. A second tassel has a channel through which the first set of lift cords pass and is attached to the second set of lift cords. In one embodiment, a top down bottom up blind, a window covering material is attached between the first rail and the second rail. The lengths of the lift cords are selected so that when the window covering material becomes tightly stacked between the two rails, continued pulling of the second tassel also pulls the first tassel raising both rails together. A second embodiment is a shade with an independent liner or a double shade. The first rail is attached to the window covering that faces the interior of the room. The second rail is attached to the liner or window covering material nearest the window. This arrangement causes the liner to rise whenever the front layer is raised to a point where the bottom of the front layer is adjacent the bottom of the liner.
