In a process of producing hemstitches by means of a zigzag sewing machine, in which straight stitches spaced from the edges of the fabrics to be sewn are formed, first zigzag stitches of a predetermined width are formed which extend between the edge of the fabrics and the straight stitches at a predetermined distance corresponding to the predetermined width of the zigzag stitches and secondly, zigzag stitches are formed which extend between the first zigzag stitches and the straight stitches. The second zigzag stitches formed are wider than the first zigzag stitches.

A stretchable interconnect includes a plurality of electrically conductive traces formed as a complex pattern on an elastic substrate. The form of the electrically conductive traces is such that when the elastic substrate is in a relaxed, or non-stretched, state each of the electrically conductive traces forms a tortuous path, such as a waveform, along the elastic substrate. The tortuous path of the electrically conductive traces provides slack such that as the elastic substrate is stretched the slack is taken up. Once released, the elastic substrate moves from the stretched position to the relaxed, non-stretched position, and slack is reintroduced into the electrically conductive traces in the form of the original tortuous path.
