How to use a special foot for a secret lightning?

Most garments need fasteners, and no one will argue that zipper is one of the most convenient options. However, it does not always decorate the finished product. Secret lightning is invisible, can be located in any seam of the product. The problem is that it is almost impossible to sew such a fastener correctly without using a special foot. We will analyze in this article how it looks and how to sew a hidden zipper.

Such paws can differ greatly from each other in shape, method of attachment, material:

Shape and mount:

  • full foot with screw;
  • interchangeable sole.

Materials:

  • plastic;
  • stainless steel;
  • coated metal, for example Teflon.

The disadvantages of plastic paws include their fragility, lower strength compared to metal. They are easily damaged by the needle, as well as on the teeth of the staff, which reduces the sliding of the foot. Subsequently, it will not be possible to stitch thin tissues without the risk of damaging them.

The advantages include low cost ease of installation.

Important! All devices are characterized by two longitudinal grooves on the sole. In these grooves, the mechanism of closing the zipper passes directly - its spiral.

There is no usual cutout for us at the lower part of the foot in the front part, it is replaced by a small hole into which the needle passes.

Set the foot

Important! If your sewing machine’s legs are completely removed, then a new accessory must be selected on the “leg”.

As a rule, you will need to unscrew the screw on the foot .

For most modern machine models, it is enough to remove the lower part of the foot from the horizontally located round jumper on the foot of the foot.

Sew on a hidden zipper

We choose the braid longer than the cutout for it by about 20 mm, which go down under the lower brace on the main fabric. Let’s figure out how to use a special zipper foot .

Work Stages:

  • We open the lock.
  • We apply it with the front side (where the slider’s tongue is visible) on the face of the product parallel to one of the edges of the cut.
  • We attach the upper part of the zipper tape with a pin to the product.
  • The bottom of the lock should be lower than the end of the cut.
  • With your thumb, we press the spiral of the clasp, as if pushing it back.
  • Raise the foot exactly as a groove above the spiral. We place to the right of the needle.
  • Sew the clasp to the mark.
  • We close the lock.
  • A closed fastener is applied to the second side of the cut.
  • The upper part of the tape is pinned to the edge of the cut.
  • We open the castle.
  • Set the foot, the spiral enters the groove of the sole of the foot to the left of the needle.
  • Sew the lock again from the top to the bottom mark.
  • We close the lock.
  • We sew the edges of the material from the mark and below, trying to continue the line with which the zipper was sewn.

If you need to shorten the synthetic zipper

Secret type fasteners are found in a small range of sizes, which is not always suitable for us.

It is not difficult to shorten such a lock, since its spiral is rather thin, therefore it does not require strong fixation:

  • We measure the necessary length.
  • Draw a new bottom line.
  • Add 1-1.5 cm to the allowance.
  • We grab the spiral at the required level with several stitches. You can duplicate superglue.
  • Trim the extra length.
  • We sew in a fastener.

Secret zippers are often located in the side seams, as well as on the back, while the junction remains invisible.
