How to Sew a Zipper in a Bag?

To install a zipper in the bag, place the right edges with the teeth together. The material and the zipper’s teeth are facing each other. Then, pin it down and sew it next to the teeth using a zipper foot. Do this with another side.

Turn both exterior and lining fabrics on the right sides together and sew around the opening, leaving space big enough to turn around. Trim the corners, then turn right-side out through the opening.

Topstitch the top edge for a clean, finished interior. Be sure to leave your zipper half open for easy sewing and to provide extra reinforcement on the ends for added strength.

Prepare the Zipper and Fabric

Prepare the Zipper and Fabric
Get started on your bag project by choosing your fabrics and a zipper. Choose a sturdy fabric for exterior fabric, like canvas or denim, with a cotton lining fabric that coordinates with your choice. An easy nylon zipper will do. Choose the length appropriate for your bag design. Using interfacing is one way to add body and stability to your bag.

Considerations of placement and size will also drive pocket design—the former informs what’s conveniently accessible, and the latter, how handy additional storage can be. Strap options range from simple fabric straps to more durable webbing.

Cut your fabric pieces to the size needed, including the lining fabric and fusible fleece.

Install the Zipper

Install the Zipper
Next, take your zipper, and its teeth should align with the edge of the fabric, thus pinning the right sides together. Run this through your sewing machine using a zipper foot; you want to get it entirely accurate. You’ll sew as close to the teeth as possible; this is for that professional finish.

Repeat on the other side of the zipper. This checking for evenness and alignment is essential here for smooth operation. For best results, use nylon zippers, as they’re easier to work with.

Maintaining the zipper involves periodic lubrication with a bar of soap or specialized zipper lubricant for smooth operation. Standard troubleshooting includes checking for fabric caught in the zipper teeth or that the zipper isn’t misaligned in case of issues.

Now, your zipper is installed correctly!

Assemble the Bag

Assemble the Bag
Place the exterior and lining fabrics on the right sides together, matching edges. Trim corners carefully and trim seam allowances so they’re clean when the bag is turned right side out.

Place the Exterior and Lining Fabrics Right Sides Together

Place your exterior and lining fabrics on the right sides together, carefully aligning the edges so that the zipper is nestled between them. Pin the layers well to prevent shifting.

This step is critical in terms of getting professional results. Sew along the pinned edge with proper sewing techniques.

Your fabric choices and zipper length must agree with your chosen bag size and lining options

Trim Corners and Seam Allowances

After sewing the exterior and lining fabrics together, it’s time to trim corners and seam allowances. This forms a very clean finish at the corners. Here’s how:

  1. Trim corners with a 45-degree cut to reduce bulk.
  2. Trim seam allowances to 1/4 inch for a clean finish.
  3. Interfacing may have to be used for added structure and stability.
  4. Always set your machine accordingly to ensure you get fantastic results for the thickness of the fabric.

Turn and Finish

Turn and Finish
Carefully turn the bag right side out through the opening you left earlier. Ensure all corners and edges are crisp, using your fingers or a blunt tool if necessary

Turn the Bag Right Side Out Through the Opening

Carefully turn the bag right-side out through the opening. Straighten the seams and corners.

Step Action
1 Finishing the gussets
2 Stuffing the lining
3 Folding in raw edges

Topstitch the top edge for a polished finish, and reinforce the corners for durability. Your zipper bag is nearly complete!

Sew the Zipper Closed

Sew the Zipper Closed
First, leave the zipper half open; this will allow you to turn the bag later on.

Manipulate the placement of the zipper so that it faces the outer fabric with teeth showing. Run your sewing machine with the needle close to the zipper teeth but not too close so that the catching of the fabric be avoided anymore. Secure with tabs at need.

Sew from one end of the zipper tape to another in smooth, even stitching. As you get close to the zipper pull, slow down your sewing, and when necessary, move the zipper pull out of your way.

Reinforce at the ends for more strength. If done correctly, your zipper should now glide with ease and length-wise, it shall perfectly match the edges of the bag to create a professional finish
