发明名称 Textile envelopes, cards and the like and methods of manufacture
摘要 A textile envelope comprises front and back panels formed of textile material having substantially the same peripheral shape, a sealing flap formed of textile material joined to a peripheral edge of the front panel, and a stiffener element situated between the front and back textile panels for stiffening at least one of the panels. A method of manufacturing a textile envelope includes the steps of situating a stiffener element between front and back panels formed of textile material, connecting overlying side regions of the front and back textile panels to each other, connecting a top region of the stiffener element to a top region of one of the front and back textile panels, and folding a sealing flap formed of textile material joined to a top edge of the front textile panel over the back textile panel.
