With this guide, we make it simple. 

Let us show you a few handy tables, links, and videos, and the sewing process will become painless.

Zippers differ in:

    • materials and techniques they’re made of (metal, molded plastic, coil, etc.),
    • uses (water-resistant; read how to sew a hidden zipper
    • shapes, sizes, widths, and lengths,
    • types of opening (closed bottom, separating);

You can identify different types of zippers with Colleen G Lea on her YouTube channel. 

Before we get to tackle particular types and learn how to sew a zipper, let’s see what it comprises. 

According to Do It Better Yourself, the parts of the zipper are: 

Parts of a zipper

Description

Teeth/chain

It’s what we imagine when we think of a “zipper.” It holds the entire zipper construction together.

Tape 

It’s the fabric around the teeth/chain. The chief part of the zipper is attached to it. 

Slider body

It’s a part that moves. It joins and separates the teeth as it slides up and down.

Pull tab

It’s what you keep between your fingers when you move the slider body up and down.

Top stop

It prevents a slider from coming off the top of the zipper

Bottom stop 

It prevents a slider from coming off of the bottom of the zipper. 

This part is present in closed bottom types of zippers but not in separating types.

Retainer box

Present in separating zippers only. It secures the zipper together and prevents a slider from coming off of the bottom of the zipper.

Insertion pin

Present in separating zippers only. It secures the opposing side of the zipper in the retainer box.

According to Sew Guide, there are at least 15 types of zippers, among which:

    • two-way separating zippers, 
    • exposed zippers, 
    • fly zippers, etc.

From Plush Addict in “Everything You Need To Know About Zippers,” you will learn:

    1. how to use particular zippers, and 
    2. which type of garment calls for which zipper;

Do It Better Yourself mentions a couple of zipper categories and tools to work with zippers:

    1. zipper foot,
    2. pliers for shortening,
    3. invisible tape, and
    4. stabilizing tape;

The easiest way to sew a zipper

Isn’t it the right time to get our hands-on experience with sewing a zipper?

Let’s start with the easiest beginner techniques. 

“You will never have to be scared off by zippers again,

—promises Sarah from Hobby Lobby in her YouTube tutorial. 

Sarah uses a sewing machine (and a handful of other sewing supplies), but it’s not the only option.

Stephanie Rubletz explains why knowing how to sew a zipper by hand may appear handy. She also reveals how to do it.

The best-known and also the easiest method of sewing a zipper is the central seam method. 

We’ll get into this technique in detail with the help of Treasurie.

Here is what you’ll need:

    1. Your zipper (if you need to adjust its length, check these instructions on Treasurie)
    2. Sewing machine with a zipper foot
    3. Sewer’s tape or scotch tape

“Learning how to sew a zipper gives the seamstress a real sense of achievement.”

—we read on Treasurie, and we couldn’t agree more!

Are you ready? Let’s browse these Treasurie steps to get skillful at sewing a zipper:  

Steps

Description Extra tip

Finish edges

Finish the edges of the sewing fabric that are about to be closed with a zipper.

You can use a serger or a regular machine with a simple zig-zag. 

When using a serger, do not cut too much of the seam allowance off. You risk making the edges too short to insert a zipper in them.

Sew edges

    1. Sew the two pieces together with the right sides together up to where you’re going to insert the zipper.
    2. Backstitch the endpoints.

Use a regular length stitch and the seam allowance stated in your pattern (typically 1/2 inch, 12mm, or 5/8 inch, 15mm).

Baste gap

If you’re not familiar with some sewing terms, check this Super Label Store blog.

Use a long basting stitch (length 4.0) on the part open for the zipper. 

You don’t need to backstitch the ends, as you will unpick them later.

Press open

Read “The Whys and Hows of Pressing Seams Open” on Craft Nectar.

Turn the sewing fabric to the wrong side and press open the seam allowance.

Let’s get back to discovering how to sew a zipper with Treasurie. What’s the next step?

Steps

Description Extra tip

Place zipper

Place the zipper face down along the basted seam on the wrong side.

Start at the top. Align the top of the zipper with the top raw edge.

Baste zipper

Put temporary tape across the zipper at the back at intervals to keep it in place. Use scotch tape or sewer tape. A zipper will stay flat with tape than with pins.

Tape well, especially the ends, to keep them relatively straight. They will separate a bit either way because of the bulk of the zipper head. When a zipper head faces down, this neuralgic point will be less bulky when sewing over it.

Pin bar

    1. Turn the sewing fabric over.
    2. Put a pin across the end (just after the metal retainer bar). 

It’s a guide to sew over. Thanks to this tiny signal, you won’t hit any metal with your needle.

Read about sewing needle and sewing threads types and tips.

We’re almost there. Now we need to stitch the zipper.

She shares two ways of sewing a zipper: 

    1. The first one works great if you need to find out how to sew a zipper pouch. 
    2. The second responds how to sew a zipper on a dress.

Now, as you are ready to sew, let’s get into it with Treasurie

On your sewing machine, change to your zipper foot.

Be sure to check the settings of your needle. It should be on the correct side to sew in the zipper.

There are two methods to sewing a zipper.

1st method 2nd method

1st step

Start on one side and stitch down the zip to the bottom.

Stitch the bottom in place at the width you need.

2nd step

Turn and then stitch a couple of rows over each other. This way, you secure the end. 

Stitch one side to the top. 

3rd step

Make the stitches the width you require at the bottom before stitching up the other side to the top.

Lift the foot and cut the threads before stitching the other side. 

When choosing your favorite method, you can try both on the scrap before you get to deal with the actual garment. 

In the last step, open the seam. Take the seam ripper to open the seam to open and close the zip freely.

How to sew a zipper in a pillow?

Learning how to sew a zipper in a pillow is among easy beginner sewing projects

Failing to be extremely precise here is not a crime. Feel free to experiment at the beginner stages of learning how to sew a zipper.

Let’s reach out to Instructables to find out how to sew a pillow cover with a zipper.

Sewing a zipper

    1. Prepare: 

      2. Mark and cut your fabric

If you’re working from an existing pillow, measure it from seam to seam, both 

      • horizontally and 
      • vertically. 

Add one inch to each measurement (i.e., for a 15×20 inches pillow, you’ll need two 16×21 inches pieces of fabric).

You can fold your fabric over and cut both pieces at once. 

To do that, draw the shape on the wrong side of the fabric, pin the two pieces together and cut it out.

      3. Sew across the edge where you want the zipper to be

Have a look at your fabric and decide where to sew the zipper in. 

It may depend on the pattern. 

You may want to show off your new zipper by putting it in the top part of the pillow cover. 

You may prefer to hide the zipper, placing it on the bottom.

Now, place the two pieces of fabric right sides together and pin. 

Lay the zipper on top and mark inside both edges (with a vertical pin).

For sewing, use a standard stitch length and 1/2 inch seam allowance.

Backstitch at the beginning of the seam to the first vertical pin. Backstitch again.

Change the stitch length to the longest basting stitch and sew to the next vertical pin. 

Change back to standard stitch length and backstitch again. 

Sew to the other edge and backstitch one more time.

      4. Place the zipper into the seam

We’re almost there!

Are you looking for some other step-by-step guide on how to sew a zipper in a pillow? 

Check these articles:

Press open the seam you just sewed and place the zipper right side down into the seam (ensure it’s centered). 

Then, pin it into place.

      5. Sew the zipper in

Start with sewing in the zipper ends.

Use the regular presser foot to sew the ends of the zipper. It will help to keep the rest of the zipper in place later. 

Install the zipper foot on your machine and roll up the edges of your pillow (it will be easier to sew it). Leave the zipper shut. 

Easiest way to sew a zipper

Backstitch at the start and sew down one side until you’re a couple of inches from the zipper pull.

Stop sewing when you get to the needle placed down in your fabric. 

Raise the presser foot and unzip the zipper past the foot. Then, put the presser foot low again.

Continue sewing until you hit the line you sewed across the end of the zipper. Then, backstitch and close the zipper again.

Backstitch and sew down the other side until you get to the zipper pull and can’t go any further. 

Backstitch, remove the fabric from the machine, rip the seam open and then finish sewing the zipper up. 

      6. Rip open the seam to expose the zipper

At this stage, starting at the end of the zipper, insert your seam ripper. Next, remove the stitches between the two vertical rows of stitching at each end of the zipper.

Catch only the basting stitches!

Pushing the seam ripper too hard can result in cutting through the zipper, and we don’t want this to happen.

Try the zipper to check if it can move along easily.

Use a lint roller to get rid of the threads’ strings that are left.

      7. Finish off the zipper

Unzip your project to sew the last part. 

Start sewing where you stopped before and continue to the end.

Apply some backstitching at the beginning and end.

The pillow cover zipper will have a lot of pressure, so it will benefit from extra security. 

      8. Sew up the pillow cover, turn right side out, and stuff

Unzip the zipper halfway to be able to turn it out to the right side later.

Keep the cover in the right sides together position. 

Pin around the edges. 

Sew around the edges with a 1/2-inch seam allowance.

Backstitch at the beginning and end.

Clip the corners to make them look nice once the pillow cover is right side out.

Added stuffing from a pillow you don’t use anymore or buy a new one.
