ABSTRACT:
A window shade comprising a base sheet-like material, such as a fabric, (1) which hangs vertically from a roller and to which is attached, by parallel narrow attachment means at intervals, a second sheet-like material of a decorative character (3) which is longer between its attachments (2) to the first material (1). If there is sufficiently excess decorative material (3) between lines of attachment (2), it folds twice between lines of attachment (2) when such a shade is rolled up. When the shade unrolls, the decorative material (3) flexes out from the base material (1) because of its greater length and forms an air-filled cell. Vertically arranged strips of these cells (18) may be formed on a single base sheet, with each strip unique in various ways to obtain a decorative effect. The shades may also be made of strips of material running the width of the shade. Decorative material which does not crease or fold tightly may be attached to the face of flexible material on a cell-by-cell basis. Variations in the dimensions of groups of cells can cause them to create decorative patterns of different types when they are viewed collectively.
