(The distance between the markings on the presser foot scale is 5 mm (3/16 inch).) 1 2 3 1 Presser foot scale 2 Length of buttonhole (Diameter + thickness of button) 3 5 mm (3/16 inch) Example: For a button with a diameter of 15 mm (9/16 inch) and a thickness of 10 mm (3/8 inch), the button guide plate should be set to 25 mm (1 inch) on the scale. 1 2 1 10 mm (3/8 inch) 2 15 mm (9/16 inch) 4 Pass the upper thread down through the hole in the presser foot. 5 You need to sew the front bar tack first. Lower the presser foot to align the marks on the foot with the mark on the fabric. 1 2 1 Starting mark on the fabric 2 Marks on the foot 6 Lower the buttonhole lever and push it back slightly. 1 1 Buttonhole lever 7 While gently holding the upper thread, start the machine. 8 The bar tacks of the buttonhole are sewn in the order shown. 3 24 1 9 Stop the machine when buttonhole stitching is finished. Note . If buttonhole sewing was interrupted, sew trial stitching one or two times on a scrap piece of fabric before continuing to sew the project. Stitching that is continued after being interrupted may be sewn incorrectly. . If thick seams are being sewn and the fabric does not feed, sew with the coarser (longer) stitch. 0 Raise the needle and the presser foot lever, remove the fabric, and cut the thread. Raise the buttonhole lever to its original a position. b Insert a pin at the end of the buttonhole stitching to prevent the stitching from being cut, and then use a seam ripper to cut towards the pin and open the buttonhole. 2 1 1 Seam ripper 2 Pin CAUTION . When opening the buttonhole with the seam ripper, do not place your hands in the cutting path, otherwise injuries may result if the seam ripper slips. Do not use the seam ripper in any other way than how it is intended. ¦ Making a buttonhole on stretch fabrics When sewing buttonholes on stretch fabric, the buttonhole stitching is sewn over a gimp thread. 1 Follow steps 1 to 6 from “Making a buttonhole” on page 34. 2 Hook the gimp thread onto the back end of the buttonhole foot, bring the two gimp thread ends to the front of the foot, insert them into the grooves, and then temporarily tie them there. 3 Set the stitch width to match the diameter of the gimp thread. 4 Start sewing. 5 Once sewing is completed, gently pull the gimp thread to remove any slack, and then trim off the excess. Adjusting buttonholes If the stitching on the two sides of the buttonhole is not the same, you can make the following adjustments. 1 Set the stitch length dial between “F” and “1.5” and sew the buttonhole on a scrap piece of fabric to observe how the material is fed. 2 If the right side of the buttonhole is too open or tight, adjust the feeding of the material with the stitch length dial. 1 2 3 1 Right side 2 Shorter 3 Longer 3 After obtaining a satisfactory feed on the right side, stitch the buttonhole and observe the feeding. 4 If the left side is too open or tight compared with the right side, adjust the buttonhole fine-adjustment screw as described in the following paragraphs. 36 SEWING BUTTONHOLES AND BUTTONS SEWING BUTTONHOLES AND BUTTONS 2 1 3 3 1 Buttonhole fine-adjustment screw 2 Left side 3 Buttonhole appearance If the left side is too open, turn the buttonhole fine-adjustment screw with a large screwdriver in the “–” direction. If the left side is too tight, turn the buttonhole fine-adjustment screw with a large screwdriver in the “+” direction. • This adjustment ensures both sides of the buttonhole are the same. Sewing buttons Stitch Name Pattern Stitch Length [mm (inch)] Stitch Width [mm (inch)] Foot Other Zigzag Stitch 3 F (1/64) Any Button Sewing Foot “M” Darning Plate 1 Measure the distance between the buttonholes and mark the fabric. Then adjust the stitch width so that it is the same as the distance between the holes in the button. 2 Turn off the machine. 3 Change the foot to the button sewing foot “M”. 4 Place the darning plate on the needle plate. 5 Turn on the machine. 6 Put a button between the foot and the fabric and make sure that the needle enters the holes without hitting the button. If it hits, see step 1. 7 At a slow speed, sew about 10 stitches. CAUTION . Make sure the needle does not hit the button during sewing. The needle may break and you may be injured. 8 Pull the upper thread at the end of the stitching to the wrong side of the fabric, and then tie it with the bobbin thread. • Use scissors to cut the upper thread and the bobbin thread at the beginning of the stitching. 5 USING ATTACHMENTS AND APPLICATIONS CAUTION . Always turn off the machine before replacing the presser foot. Otherwise, injuries may occur if the foot controller is accidentally pressed and the machine starts sewing.
