How to sew a men's thong

There are many different ways to sew in a zipper. The zipper for classic women's trousers is sewn in differently than the zipper for men's trousers. Today is about how you would sew a concealed zipper into a pair of jeans. I sew the whole thing using the example of the pants for my little son. In my previous report, I showed you how to sew the banana pockets of your pants. Now we continue with the sewing together of the front part of the trousers, which includes the sewing in of the zipper. Oops, now I've used the word "sew" in a pretty inflationary way. 😉 But this word is also really difficult to replace!

Required material for sewing a zipper for a pair of pants:

  • Outer fabric
  • Lining fabric
  • zipper
  • scissors
  • matching color yarn
  • Iron-on fleece
  • Pins
  • Tailor's Chalk
  • Zipper foot (The zipper foot is a very narrow sewing machine foot that can be used to sew very close to the teeth of the zipper.)

How do you sew a zipper into a pair of pants?

In the following picture you can see all the pattern pieces that you need for the processing of a zipper.

A stirrup fleece is ironed onto the left slit part. To do this, cut out the iron-on fleece in exactly the same size as the left slit part and iron it onto the cut part with a lot of pressure. The temperature of the iron with which the glue is set is shown on the fixing insert.

Now you can pierce the left side of the left part of the slit. This makes the fabric more stable and durable.

The right slit part is folded in the middle and ironed. So the fabric is double. This is supposed to protect the zipper from tearing out. The open side and the lower edge are then stitched over.

In the next step, put the right and left front pant legs right sides together. The right part of the front trousers protrudes approx. 1 cm in the upper area. But that can vary depending on the trouser cut. You sew the seam with a seam allowance of 1cm. Only the lower half of the central seam is sewn. The seam ends 1 cm after the protruding part of the right front trouser part.

The front trousers parts are unfolded. You place the open zipper with the left side up on the right front trouser part. The teeth of the zipper point to the left.

Then place the right slit part on the zipper, flush with the edge. Feel free to poke a few pins to make sewing easier. Here again step by step in three pictures this step:

Then fold the right slit part to the side and sew close to the edge on the front trouser leg along the zipper teeth. The seam line starts at the waistband and ends with the lower edge of the right slit part. It is best to use the zipper foot for this.

Now place the left slit part right sides together on the left front leg, flush with the edge. If you want, you can again use pins to fix it. The left slit part is sewn on with a seam allowance of 1 cm.

Turn the left slit part onto the left side of the front pants. Stitch the edge close to the crotch seam.

Now turn the front pants over so that the left side is on top. Close the zipper. The part of the zipper that has not been sewn on is now in its correct position. Pin the zipper on the left slit part. You have to be careful not to let the zipper slip. Fold the right slit to the side and pin it in place.

Open the zipper and sew the loose half of the zipper onto the left slit part with a zipper foot.

Now you stitch the left slit part to the left front half of the pants. To do this, leave the right slit part, fixed with a pin, folded to the side. Turn the pants right side out and mark the desired course of the seam line with chalk. Then sew the line.

Finally, a few more bars are set, as can be seen in the two following pictures:

This is what the pants look like when the zipper is sewn in and all latches have been set:

Sewing in a zipper is not that easy. But with a little practice it is definitely possible. If you have any questions, I'll be happy to answer them. Just send a short email to [email protected]
