Sewing guidance
Joining and overcasting
If you are not going to press the seams open then it is
possible and timesaving to join and overcast simultane­
ously. Seams sewn in this way will be fine and supple.
Overcast stitch (1) is usually used for sewing light and
medium non-stretch materials.
Heavier non-stretch fabrics are best sewn with the
overlock stitch (2).
The overcast stitch is also preferable for sewing light
stretch fabrics while the overlock stitch is used for other
stretch materials.
When sewing stretch fabrics these stitches are sewn
with a space between the side stitches which makes the
seam elastic.
The stitch length and width will be automatically
sdwCtcdi to suit your fslDric.
Join and overcast direct where the edge is cut with a 5
mm seam allowance. Using the basic setting, allow the
fabric edge to run along the right, inside edge of the
presser foot.
Presser foot J is fitted with a pin to prevent the fabric
edge from puckering.
Topstitching
Topstitching is used for sewing down seam allowances
and as a decorative stitch on facings, collars, pocket flaps
etc.
Normally straight stitch is used but in some cases other
stitches give better results.
Topstitching should always be sewn on double fabric.
Some fabrics require interfacing to attain the full effect
of topstitching.
You will find more about topstitching and how to use
the various needle positions on page 32.
