  • Patent number: 4346875
    Abstract: For rolling out dough, a flexible pastry cloth includes a plurality of first fastener parts or buttonholes spaced successively around its margin. A plurality of suction cups, each securingly engageable with a flat surface, such as a tabletop or countertop, each have a second fastener part or button individually connectable removably with a corresponding part on the cloth. Engagement of the cups with the surface permits stretching of the cloth to enable rolling of the dough against the surface through the cloth. A further improvement adds a second flexible cloth affixed atop and overlying the first.
