Abstract
A dual-laminate honeycomb panel permits the use of two or more different materials to form a single panel. In this manner, a retractable covering for an architectural opening may be formed that has a different appearance depending upon which side of the panel is being viewed. The resultant panel is formed by attaching a plurality of elongated precursor tubular cells, wherein each precursor tubular cell itself comprises two strips of material attached to one another.
