Sewing
Darning
To mend a small hole or tear, you can either do automatically by using
the darning stitches on the machine or darn your tear manually using
by doing Free-motion darning.
Automatic darning
The darning stitches no. 64 and no. 65 can be used for strengthening
damaged areas of fabric.
1. Choose stitch no. 64 or no. 65.
2. Change the pattern length to the length of the tear of touching the +
and -.
3. Stitch over the damaged area.
Programmable Darning
1. Choose stitch no. 64 or no. 65.
2. Touch the program icon.
3. Stitch over the damaged area to the required length.
4. Press the reverse button; the machine fi nishes sewing the darning
program and the darning length is saved. The saved darning length
can now be repeated as often as needed.
Stitch no. 64 sews lengthwise only; stitch no. 65 is for darning
lengthwise and crosswise and is more durable.
Note: To give the best strength to the darning stitch it should be slightly out of square.
Balancing the darning stitch
Depending on the type of fabric, the darning pattern may shift slightly
out of square. You can balance the program using the adjustment
capability.
Darning with the elastic stitch
Stitch No. 4
The elastic stitch no. 4 is very suitable for repairing small holes and
slightly damaged areas. This is most suitable for light-weight fabrics.
Reduce the stitch length and sew rows of stitches over the damaged
area until it is well covered. Make sure the stitch rows overlap. No
additional backing is needed for these slightly damaged areas.
