Sew 4-step buttonholes_______
Prepare
1. Take off the all purpose foot and attach the
buttonhole foot.
2. Measure diameter and thickness of button and add
0.3 cm (1/8") for bar tacks; mark buttonhole size on
fabric.
3. Place fabric under the foot, so that marking on the
buttonhole foot aligns with starting marking on fabric.
Lower the foot, so that the buttonhole center line
marked on the fabric aligns with the center of the
buttonhole foot.
Adjust the stitch length dial in the " \ w .= h " to set stitch
density.
Note: density varies according to the fabric. Always
test sew a buttonhole.
Follow the 4-step sequence changing from one step to
another with the stitch pattern selector dial. Take care
not to sew too many stitches in stages 2 and 4. Use
seam ripper and cut buttonhole open from both ends
towards the middle.
Tips:
- Slightly reducing upper thread tension will produce
better results.
- Use a backing for fine or stretchy fabrics.
- It is advisable to use heavy thread or cord for stretch
or knit fabrics.
- The zig-zag should sew over the heavy thread or cord.
