A light control window covering comprising a first relatively translucent sheet (50) material, second relatively translucent sheets (51) of material, disposed parallel to said first sheet, a plurality of strips (60) of relatively opaque material, each have edge portions, said strips having their edge portions adhesively bonded to said first sheet (50) and said second sheet (51), respectively, whereby central portions of said strips, in a first closed position of said window covering, are substantially planar and extend substantially parallel to the first and second sheet (50,51), effective at least partially to block transmission of light and, in the second position of said window covering extend generally transverse to said first and second sheets, effective to transmit light between said strips. <IMAGE> |
