Abstract
A vane for an architectural covering, such as of the type used in a window opening, is designed for vertical suspension so as to resist twisting along its length. The vane is constructed in a tubular configuration and may have one or more internal hollow cells. The external configuration of the vane may simulate an air foil or have other related configurations. The vanes are preferably made of a material having diagonal, dimensional stability or memory, i.e. the ability to resist stretching in a direction diagonal to the length or width of the material.
