Twin needle topstitch hem
With the twin needle topstitched hem the hem is sewn, the edge finished and a decorative effect is achieved on the right side of the fabric in one operation. Use twin needles with a minimum needle spacing of 4 mm (size 4.0/90).Fold and press up the hem along the hemline. From wrong side, baste in place approx. 1/8" (2-3 mm) from raw edge. Attach the Edge Guide to the machine. From the right side of the fabric, using the basting line as a guide, position the edge guide so the twin needles straddle the basting line. Topstitch the hem in place. The bobbin thread will enclose the raw edge as the hem is sewn.
