How to Sew a Zippered Pocket

If you have ever wanted to add a zippered pocket to your bag or other sewing projects, this tutorial will walk you through how to do it! This zippered pocket tutorial is a companion article for my 7th Street Tote, August Tote and Eva Quilted Tote patterns but these techniques can certainly be applied in other bag patterns.

To add just a regular open pocket inside a bag, aka slip pocket, then check out my tutorial How to Sew a Slip Pocket for another pocket option to keep your bag organized!

A zippered pocket can be added to the inside or the outside of a bag for added storage or to keep personal items secure. Throughout this tutorial I’ll be referring to measurements used in the 7th Street Tote pattern, but they can be easily changed depending on your project.

I was pretty intimidated to sew zippers when I first started sewing, but the more I practiced, the more confident I became! If you’re looking for a great oversized tote bag pattern and want some more zipper practice, check out my Lakeview Tote pattern which has an option to add a zippered pocket to the inside.

Here is a quick video showing an overview of the process.

Some Things You’ll need

This page contains some affiliate links to products and I may receive a small commission for purchases made through these links (at no extra cost to you).

• Fabric – lightweight to midweight cotton fabric
• 1/4″ double stick fusible tape – optional, but is really nice when you want the zipper to stay in place before topstitching around.
• Fusible interfacing – optional, but the sturdiness from the interfacing makes it easier to sew the zipper.
• 7″ zipper (You can also use a longer zipper and cut it down to the length you need – That’s what I did in this example)
• Ruler – this is my favorite quilting ruler
• Rotary cutter or fabric scissors
• Cutting mat – a must have if using a rotary cutter
• Iron

Pattern Pieces Needed

I have my pieces cut out and ready to go for this tutorial – the lining pieces for my tote bag, and two smaller pocket pieces in lining fabric.

You only need one of the lining pieces for the zipper pocket – this is what you will be cutting a “window” out of for your zipper. The pocket piece size I’m working with is 9″ x 7″ which is a pretty typical zipper pocket size for inside a bag. The measurements I’m using are for a 7″ zipper, but if you want a bigger pocket with a longer zipper, make sure your pocket pieces is at least 2″ wider than the pocket opening. My pocket opening is 7″ (the length of my zipper between the metal stoppers) so my pocket piece is 9″ wide.

Let’s get started!

Step 1: Draw markings for pocket Opening

Mark the center of one lining piece. Cut a small piece of fusible interfacing measuring about 2” x 9” (this is optional but it does provides stability while installing the zipper). Mark the center of the interfacing and line it up with the Lining center mark and 4″ down from the top. Press interfacing with an iron to the wrong side of the lining.

On the interfacing, mark long straight lines as follows: (you will not see these lines as they will be on the wrong side of the lining).

5” from top (this is where the center of the zipper will be)
1/4” above center line
1/4” below center line

Find the center on the interfacing using your lining center mark. Close up the “box” by marking vertical lines 3.5” from the center on the right and left.

Draw diagonal lines from each corner to the middle line as shown below.

Step 2: Pin Pocket Bag to Lining

Turn the lining over so the right side is facing up. Take one of the pocket pieces and mark the center. Draw a horizontal line on the Lining 3.5” down from top with chalk or washable fabric marker (this will show on the right side of the fabric).

With right sides together, line up the pocket piece along the line you just drew and centered using the center marks. Place a pin in each corner of the pocket – you want the pins to be in the corners so they are out of the way for the next step.

Step 3: sew Pocket to Lining

Turn everything over so the wrong side of the lining is facing up. Stitch along the outside of the box using the lines you drew as a guide. Tip: Use a smaller stitch length to help with accuracy.

Step 4: Cut opening and pull pocket through

Cut along the middle line until you reach the points of the triangles at each end. Tip: You can get started a rotary cutter and then finish with scissors.

Cut along the diagonal lines into the corners as close as you can but without cutting the stitches.

Pull the pocket through the opening you just made from the right side to the wrong side of the lining. The right side of the pocket should be facing up. Press around the edge of the opening, making sure that the pocket lining isn’t showing from the right side.

Tip: If the corners are still rounded, you can check to see if you still have room to clip a little more into the corners – this will help to get pointed corners.  

Step 5: Position zipper and sew

With the wrong side of the lining facing up, Apply 1/4” fusible tape (Amazon affliate link) flush along the top and bottom edge of the zipper opening and press with iron to fuse. Remove paper backing before the next step (If you have trouble removing the paper backing cleanly, it may need more pressing with the iron). 

*The fusible tape makes installing the zipper easier and helps to keep the zipper in place when sewing, but you can use pins if you want.

Decide which way you want the zipper to open. With the zipper face up on a table, place pocket opening on top of zipper (right side up), centering the zipper where you want it. Make sure the metal stoppers are out of the way before topstitching. Usually the fusible tape is sticky enough, but you can press again with the iron if needed.

Using a zipper foot, sew close to the edge of the opening, all around the opening. When needed, raise the presser foot and move the zipper pull out of the way when you come to it.

Step 6: Sew pocket pieces together

Turn everything over so the wrong side of the lining is facing up. Place the other pocket piece on top right sides together and line up the raw edges. Pin just the pocket pieces together and sew all around the edges with a 1/4” seam allowance. Make sure to move the bag lining out of the way when needed.

And you’re done! You can wipe the markings away with a damp cloth at this point and continue on with the pattern instructions. In the 7th Street Tote, the next step is sewing the Lining pieces together to finish up the lining for the bag.

After the lining is finished, the recessed zipper comes next so head over to my tutorial How to Sew a Recessed Zipper to help walk you through those steps.
