ABSTRACT:
A method utilizes a group of four stitchings and a nylon cord which are implemented into the seam of an article of clothing to create a tear-resistant seam. The first step in the sequence of stitching is a serging stitch which attaches the two pieces of material together, creating a seam. The second step is to sew a nylon cord in the seam created by the serging stitch by way of a first zigzag stitch. The first serging stitch and the first zigzag stitch are adjacent to each other and do not overlap one another. The third step is to stitch two lines of straight stitching adjacent to each other and directly adjacent to the first zigzag stitch of the second step. The fourth and final step is a second zigzag stitch which will overlap the first zigzag stitch and the first of the two lines of straight stitch of the third step. Upon completion of these four steps, the newly created seam is tear-resistant.
