• Carefully cut open your buttonhole. Tip: For Àne buttonholes, you can reduce the buttonhole width with the stitch width dial (27) down to approx. 3 mm. Use the center needle position . Carfully cut open your buttonhole with scissors or a seam ripper. Utility stitches and practical sewing Standard buttonhole with gimp thread A To sew especially durable buttonholes, on heavy fabrics, knits or sportswear, we recommend using a gimp thread. On knits the gimp thread is particularly important to prevent the buttonhole from stretching. • Lay the gimp thread over the rear protrusion A and pass the thread ends B underneath the presser foot towards the front. • Clamp the threads to the left and right of protrusion B. • Slide the buttonhole runner as far forwards as possible and sew the buttonhole as described for your select model. • Pull the loop of the gimp thread into the buttonhole and cut the threads. 35
