Abstract
A light-control window covering includes a first sheet of sheer material, and a second sheet of sheer material spaced apart from the first sheer sheet of material. A plurality of vanes having a first face and a second face, a center region and a first and a second longitudinal margin, the first face of each vane being ultrasonically welded to the first and second sheets of sheer material along the respective first and second longitudinal margins. The vanes are welded to the first and second sheer sheets of material, while the first and second sheer materials are spaced apart and parallel to one another. The welded first and second sheets of sheer material and vanes are then shifted from a light-passing position to a light-blocking position and heat set.
