How to sew a classic trouser fly front zip

Welcome to a new sewing class, in today’s lesson, I’m going to teach you how to sew a classic trouser zip.

Today’s class begins by downloading and printing the patterns so we can sew this zip together.

You will find these patterns just below the video of today’s class, remember to print them in real size.

Once downloaded and printed I will explain the different parts of the patterns and their markings.

Remember to pre-shrink the fabric before cutting and iron the zipper so that the tape does not shrink when you are sewing it.

We usually start by sewing the front crotch of the trousers but we usually leave a few centimetres unstitched so that we can close this seam later without problems.

Although you usually start by putting the zip, the crotch is usually closed completely when you finish the trousers.

When it comes to putting a zip on a pair of trousers, we are going to need to change the foot of the machine for a special foot for zips to be able to sew very close to the teeth of the zip.

First, we will sew the left part of the zip where we will have to cut an area to make sure that the zip is balanced and hidden.

Also on the left side, we will add a zip guard, this will make sure that the zip teeth will not touch the skin and thereford we will prevent our client from getting hurt.

Then we will sew the right of the zip, where we will add some decorative stitching that also has the function of holding the zip on the front.

These patterns are designed to be used with a 13cm (5in) zip but you can trim the zip.

As you already know, the best way to learn to sew is by practising, so for today’s class, I’m going to ask you to sew a classic fly zip.

Use the patterns that you will find just below the video.

The final length of the zip is 13cm (5in) but you can shorten a zip if you don’t have one of this size.

Remember to press the final sample so that it has a better finish.

Please try to send me photos where your final result can be seen clearly, also if you want better comments send me photos of your sewing process.
