ABSTRACT:
A balloon-type shade utilizes bands of low-friction material, attached to a flap on the shade, for guiding the drawstrings at their points of directional change from vertical to horizontal. This permits the shade to be prestrung, independently of any rigid mounting rod, and thereby enables shipment in a flat, folded condition.
