Abstract: A do-it-yourself-without-tools window shade which is width adjustable and installable by the consumer at the point of installation without the use of tools or cutting elements is disclosed. The window shade includes a composite sheet structure of a plastic sheet and a fabric sheet laminated to one another by a conventional plasticizer based adhesive under the action of heat and pressure. The composite sheet structure includes a plurality of parallel cut lines which extend all the way through the fabric layer and into the plastic layer to a predescribed depth thereby enabling the consumer to strip the sheet structure to its proper width.
