Abstract
In a method of making rolls or strips of material having no flaws except joints a supply of material, such as a roll of fabric is inspected for flaws. If any flaws are discovered portions of the material containing the flaws are cut away. The material is attached together after each portion is removed to create a joint for each reattachment. The portions that are cut away are sized so that the joints will be separated by a multiple of a selected distance from one another. The resulting material can then be fabricated into a panel of window covering material in which all the joints are co-linear along a perpendicular to the surface of the material. The joints are positioned so that they will be on a cut line for subsequent processing. In one embodiment the material is wound into a tubular structure that is cut along the joints to form a panel of window covering material.
