An apparatus comprising:

• a friction surface configured to selectively restrain movement of a first facing of a window shading, the first facing being coupled to a fabric supply roller of the window shading at a first position on an outer surface of the fabric supply roller, and coupled to a second facing of the window shading through a plurality of vanes extending between the first facing and the second facing,
• wherein rotating the fabric supply roller of the window shading to extend or retract the second facing, while restraining movement of the first facing with the friction surface, adjusts an angular position of the plurality of vanes.
