ABSTRACT OF THE DISCLOSURE An improved method of hem-stitching employing a zigzag sewing machine having a vertically and laterally reciprocating needle adapted to penetrate into a sewn fabric to form lock stitches with upper and lower threads, and having a feeding device operated to feed the fabric in one direction and in the opposite direction, the hem-stitching method comprises: a step to produce at least two stitches at one point adjacent to the edge of the fabric with the feeding operation in one direction; a step to produce at least two spaced apart stitches with the feeding operation in one direction, said stitches being spaced from each other in a vertical direc- tion and laterally spaced from the stitches produced at said one point, and a step to produce at least two fixing stitches with the feeding operation in one direction between the stitches produced at the one point and the stitches spaced from each other in the vertical direction and laterally spaced from the stitches at the one point, the fixing stitches being vertically spaced from each other and connected to the stitches produced at the one point with the feeding operation in one direction, and also connected to the said spaced apart stitches with the feeding operation in the opposite direction; the improved method avoids the troublesome operation of exchanging the presser foot and the need for an additional attachment in the sewing machine.
