    摘要: A Roman shade is formed from plastic sheet material having a heat sealable characteristic. Transverse, horizontally extending pleats are folded in the shade and are heat sealed to permanently secure them. A bottom hem is formed by folding and heat sealing a bottom portion of the shade together, and the terminal end portion of the shade may be joined to a bottom horizontally extending pleat, either within or adjacent the pleat, so that the bottom pleat and hem are formed at the same time. Aperture, through which shade pull strings are guided, are provided in the pleats.
