Abstract

A window covering is described wherein at least one translucent or transparent sheet is suspended vertically and has a plurality of parallel vanes projecting rearwardly therefrom. The vanes are formed from fabric material which has either been rigidified with a rigidifying compound or rigidified by the formation of a pocket into which a rigid slat is inserted. Variations are provided for varying the flexibility of a hinge defined along a juncture line between the vanes and the fabric sheet.
