One-Step Buttonholes

With one-step buttonholes, you can make buttonholes appropriate to the size of your button.

One-step buttonholes are sewn from the front of the presser foot to the back, as shown below.

  1. Reinforcement stitching

 

  1. Select a buttonhole stitch, and attach buttonhole foot “A+”.

    Position the upper thread under the presser foot by guiding thread through the hole in the presser foot before attaching the buttonhole foot “A+”.

    IMPORTANT
    • When attaching and removing buttonhole foot “A+”, do not apply excessive force to the presser foot, otherwise it may be damaged. In addition, be careful not to hit the needle when attaching and removing buttonhole foot “A+”.
    • Before attaching the presser foot, check that there is enough thread in the bobbin.
    • Sew trial stitches on fabric that is the same as that used in your project, referring to Fabric/Thread/Needle Combinations.
    • Camera detects "A+" and the 3 dots of the button holder to determine the buttonhole size. Do not touch the camera. (Refer to Names of Machine Parts.)
      Do not peel the “A+” sticker off buttonhole foot “A+” or cover the sticker and the 3 dots with the upper thread, etc. Otherwise the camera cannot detect the presser foot or buttonholes cannot be sewn.
    • If the fabric does not feed correctly, such as when sewing stretchy fabrics, install the buttonhole foot stabilizer. (Fabric Cannot Be Correctly Fed)

  2. Mark the position and length of the buttonhole on the fabric.

    1. Marks on fabric
    2. Buttonhole sewing
      • The maximum buttonhole length is about 47 mm (approx. 1-3/4 inches) (diameter + thickness of the button).

  3. Pull out the button holder plate on the presser foot, and insert the button that will be put through the buttonhole. Then tighten the button holder plate around the button.

  4. Align the presser foot with the mark on the fabric, and lower the presser foot.

    1. Mark on the fabric
    2. Marks on the presser foot
      • After lowering the presser foot, make sure that there is no gap in 1.

  5. Gently hold the end of the upper thread, and then start sewing.

    Feed the fabric carefully by hand while the buttonhole is sewn.

    • Once sewing is completed, the machine automatically sews reinforcement stitches, and then stops.

  6. Press (Thread cutter button) once. Raise the presser foot, and then remove the fabric.

    • When using scissors to cut the threads, press (Needle position button) to raise the needle, raise the presser foot, and then pull out the fabric before cutting the threads.

  7. Insert a pin along the inside of one of the bar tacks, and then insert the seam ripper into the center of the buttonhole and cut towards the pin.

    1. Seam ripper
      CAUTION
      • When using the seam ripper to open the buttonhole, do not put your hand or finger in the path of the ripper. The ripper may slip and cause injury.
      • For keyhole buttonholes, use the eyelet punch to make a hole in the rounded end of the buttonhole, and then use the seam ripper to cut open the buttonhole.

Odd Shaped Buttons/Buttons that Do Not Fit into the Button Holder Plate

Add the button diameter and thickness together, and then set the button holder plate at the calculated value.

The distance between the long markings on the presser foot scale is 5 mm (approx. 3/16 inch).

  1. Presser foot scale
  2. Button holder plate
  3. Completed measurement of diameter + thickness
  4. 5 mm (approx. 3/16 inch)

    Example: For a button with a diameter of 15 mm (approx. 9/16 inch) and thickness of 10 mm (approx. 3/8 inch), align the scale with 25 mm (approx. 1 inch)

    1. 10 mm (approx. 3/8 inch)
    2. 15 mm (approx. 9/16 inch)

    Setting the Slit Length

    The calculated value can also be set in the screen instead of setting the button holder plate.

    Fabric Cannot Be Correctly Fed

    If the fabric does not feed (for example, because it is too thick), first increase the stitch length setting.

    If the fabric still does not feed correctly, such as when sewing thick fabrics or stretch fabrics, install the buttonhole foot stabilizer, and then feed the fabric between the buttonhole foot stabilizer and buttonhole foot “A+”. Attach the buttonhole foot stabilizer to buttonhole foot “A+” before attaching buttonhole foot “A+” to the presser foot holder.

    2. Fabric

    Sewing Thick Fabrics

    Place a piece of folded fabric or cardboard beside the fabric being sewn to level the buttonhole foot and allow for easier and even feeding.

    1. Presser foot
    2. Thick paper
    3. Fabric

    Sewing Stretch Fabrics

    When sewing on stretch fabric, sew the buttonhole stitches over a gimp thread.

    • Attach stabilizer material to the back of stretch fabrics to prevent them from stretching.

    1. Hook the gimp thread onto the back of presser foot “A+”. Insert the ends into the grooves of the presser foot, and then temporarily tie them there.

      1. Gimp thread
      2. Upper thread

    2. Select a stitch and start sewing.

      • Adjust the stitch width to the thickness of the gimp thread.

    3. Once sewing is completed, gently pull the gimp thread to remove any slack, and trim off any excess.
