An apparatus for cutting a window covering comprises a saw for cutting the window covering. An engagement member locates the center of the window covering. A clamp assembly moves the window covering relative to the first saw and the second saw. A dust collection system comprises a shroud substantially surrounds the bottom of the saw blade where the shroud is connected to a vortex dust collector. In one method of operating a window covering a first end of the window covering is located at a known first position relative to the package. An engagement element is provided on the package that is located at a known second position on the package. The engagement element is moved a distance from a saw to obtain a final dimension of the window covering where the distance is calculated using the first position and the second position. A method of operating a cutting machine comprises automatically cutting a valance to a different length than the window covering.
