Abstract
A covering material for a window covering assembly is provided that includes a plurality of formations, wherein an indicator marking is placed on the covering assembly at a known increment of the formations. The method of making the covering material includes, providing a web of material, printing a plurality of stripes on the web, and folding the web to create a window covering material having a plurality of formations. In one embodiment, the stripes are positioned such that a first face of the window covering material exhibits a color different than the remainder of the window covering material once folded. A longer stripe extends away from the first face to create the indicator marking. In another embodiment, the markings are made with a selectively observable material so that the covering material must be placed in a particular light to be viewed.
