Selector setting: BO
Stitch Width:
2Vi or 3
Throat plate: General purpose
Stitch length: 12
Cording foot
Blind stitching the final step of a zip insertion
results in a fine finish that is almost invisible and
comparable
to hand sewing. Particularly suitable
for chiffons, sheers, velvets and all delicate fabrics
where top stitching would be too harsh.
Allow a Vs" seam allowance. Start the insertion
in the regular way but omit final step.
Work from the right side of the garment and pin
the front of the zip tape into position.
Roll the work over finger to ease fabric and pin
through all thicknesses. Baste about Vs" from seam
line to provide guide for blind stitching. Remove
pins.
Set stitch and adjust cording foot to the right
side of the needle.
Turn garment inside out. Place zip tape over
feed of machine and turn back the front section of
garment to line of basting, creating a soft fold.
Position work so that the straight line of stitching
is made through front seam allowance and zip tape,
and the sideways stitch pierces a few threads of the
fold. Lower presser bar and stitch slowly. Remove
bastings. Press.
