How to Add a Zipper to a Tote Bag ?

Adding a zipper can make your tote bag more secure and versatile. Whether you’re upgrading a store-bought bag or finishing a handmade one, the process is straightforward with the right tools.

Materials You’ll Need

• Tote bag (finished or almost finished)

• Zipper (nylon or metal, matching or contrasting color)

• Sewing machine (with zipper foot)

• Matching thread

• Fabric scissors

• Pins or clips

• Seam ripper (if altering an existing bag)

• Optional: bias tape or extra fabric for a zipper facing

Step 1: Measure and Choose Your Zipper

Measure the tote bag’s opening. Choose a zipper that’s 1–2 inches shorter than the opening so it fits neatly without bunching.

---

Step 2: Prepare the Bag Opening

If the tote bag is already finished:

1. Use a seam ripper to open the top seam where you want the zipper.

2. Press the edges flat with an iron.

If you’re adding the zipper before assembling the bag:

1. Work with the flat panels before sewing the sides and bottom.

Step 3: Pin the Zipper in Place

1. Place the zipper face-down along the top edge of the bag.

2. Align the zipper tape edge with the raw edge of the fabric.

3. Pin or clip in place to prevent shifting.

Step 4: Sew the First Side

• Attach the zipper foot to your sewing machine.

• Stitch close to the zipper teeth on the first side.

• Keep the zipper pull out of the way by lowering the needle, lifting the presser foot, and sliding the pull past the needle.

Step 5: Sew the Second Side

1. Repeat the process for the opposite edge of the zipper.

2. Ensure both sides are aligned so the bag closes evenly.

Step 6: Finish the Ends

To prevent fraying or catching:

• Sew a short bar tack across both ends of the zipper.

• If desired, cover the ends with small fabric tabs for a polished look.

---

Step 7: Close and Test

• Zip and unzip several times to check smooth operation.

• Reassemble the rest of the tote bag if you installed the zipper before finishing.
