  • Patent number: 4447483
    Abstract: A reticular needlework fabric (10, 16) comprising a unitarily molded network of strands (12). The network has a plurality of spaced strands (12) extending parallel to a first axis, and a plurality of spaced strands (12) extending parallel to a second axis. A selected number of marker strands (14) are included among the strands (12) parallel to at least one axis. The marker strands (14) are separated from each other by a selected number of strands (12) and have molded-in features rendering them visually distinguishable from the remaining strands (12). The method of the invention for making such a reticular needlework fabric (10, 16) formed by channels (22) formed in at least one of the opposed faces (20) of a two-part mold (17) includes the steps of altering selected marker strand channels (24) so as to produce molded-in features in the marker strands (14) molded therein, rendering them visually distinguishable from the remaining strands (12).
