This invention is directed to a window shade whose width can be decreased, without cutting instruments, to conform to the size of the window opening into which the shade is to be mounted. The window shade includes a roller and a shade secured to the roller having at one or both edges a plurality of spaced strip lines, preferably invisible, extending from end-to-end parallel to the shade edges. The strip lines permit hand-stripping of discrete widths of the shade while the shade is rolled on the roller. The roller includes, substantially coincident with the strip lines of the shade, a plurality of longitudinally spaced, circumferentially extending strip lines permitting removal of a corresponding discrete length of the roller. In accordance with the invention disclosed, the shade can be conveniently shortened by the consumer in the home, without the need for cutting of the shade, thus eliminating the need for cutting machines.
