□ How to sew buttonholes (one-step buttonholes)
Buttonhole sewing is a simple process that provides reliable
results. However, it is strongly suggested to always make a
practice buttonhole on a sample of your fabric and interfacing.
Making a Buttonhole
1. 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
(Q). Set stitch length dial to (czi); Adjust stitch width (3 dial
machine) to desired width.
3. Lower the presser foot aligning thé marks on foot with the marks
on the fabric (A). (The front bar tack will'be sewn first.) (Align the
mark on the fabric (1) with the mark on the foot (2).
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 is sewn.
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 (Q). Set stitch length dial to ( cid ).
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.
