  • Fabric having a removable monofilament guide
    Patent number: 7421961
    Abstract: The use of monofilament line to form a grid in the cross stitch fabric corresponding to the grid in a cross stitch pattern to facilitate the cross stitching process, after which the monofilament line can be easily removed by pulling from either end. The monofilament line has the distinct advantage of being resistant to piercing by the needle and cross stitch thread during the cross stitching process, and thus not being woven into the design as guide thread would do.
