of widths as indicated on the pattern selector, you can sew any width you desire.
Since this is a range, you may set the dial between the illustrated widths.
OVERCASTING
This is one of the more frequently used
zigzag stitches in garment construction.
You may want to overcast along the raw
edge of each seam allowance or fold the
raw edge toward the garment and stitch.
Fig. 1 shows the raw edge finished.
Fig. 2 illustrates the folded edge stitched.
Stitch so the needle pierces the fabric
just short of the outside edge. Raw or
worn edges of older garments can be
overcast to prevent further raveling.
INTERFACING DARTS
To reduce bulk of interfacing darts, cut
interfacing down center between dart
lines. Overlap cut edges, matching dart
lines. Zigzag stitch along marking line
from point to wide end of dart. Trim
both raw edges close to stitching.
