Using tailor's chalk, mark the position of the buttonhole on the fabric. 2. Attach the buttonhole foot and set the Pattern Selector Dial to " ". Set stitch length dial to " ". Set the stitch width at "5". The width however may need to be adjusted according to the project. Sew a test first to determine this. 3. Lower the presser foot aligning the marks on foot with the marks on the fabric (A). (The front bar tack will be sewn first.) (Align the mark on the fabric (a) with the mark on the foot (b).) 4. Open the button plate and insert the button (B). 5. Lower the buttonhole lever and gently push it back (C). 6. While lightly holding the upper thread, start the machine. 7. Buttonhole stitching is done in the order (D). 8. Stop the machine when the buttonhole cycle has completed. Making a Buttonhole on Stretch Fabrics (E) When sewing buttonholes on stretch fabric, hook heavy thread or cord under the buttonhole foot. When the buttonhole is sewn the legs will overcast the cord. 1. Mark the position of the buttonhole on the fabric with the tailor's chalk, attach the buttonhole foot, and set the pattern selector dial to " ". Set stitch length dial to " ". 2. Hook the heavy thread onto the back end of the buttonhole foot, then bring the two heavy thread ends to the front of the foot, insert them into the grooves and temporarily tie them there. 3. Lower the presser foot and start sewing. *Set the stitch width to match the diameter of the gimp thread. 4. Once sewing is completed, gently pull the heavy thread to remove any slack, then trim off the excess. 19
