How to Sew with Rainbow Zipper Tape for Colorful Bags

Quick answer

To sew rainbow zipper tape onto a bag, use a #5 nylon zipper tape and a matching #5 pull, then follow a simple pinning and stitching process to keep the tape straight and the colors aligned.

How to sew rainbow zipper tape onto a bag

1. Cut the tape to length: Measure the opening of your bag and cut the rainbow zipper tape about 1 inch longer than the opening. Because the tape is sold in 3-yard precut lengths that are not continuous, you may need to piece together shorter sections if your project is longer than 3 yards. Always cut a little extra to allow for seam allowances and finishing.
2. Attach the zipper pull: Insert the #5 nylon pull onto the tape. Slide the pull over the open end of the tape and gently wiggle it until it clicks into place. If the pull is tight, use a pair of pliers to gently squeeze the sides of the pull to open it slightly. Test the pull before sewing to make sure it slides smoothly along the tape.
3. Pin the tape to the fabric: Place the zipper tape right side up along the seam of your bag fabric, aligning the edge of the tape with the fabric edge. Pin every 2–3 inches to keep the tape from shifting. The rainbow stripes should be visible and straight. Check that the stripes are parallel to the seam line before you start stitching.
4. Stitch the tape in place: Using a zipper foot, stitch close to the teeth of the tape. Sew slowly and remove pins as you go. Backstitch at both ends to secure the tape. For thicker fabrics, use a longer stitch length (3–4 mm) to prevent skipped stitches. Avoid stitching over the zipper teeth—this can break your needle or damage the tape.
5. Finish the ends: Trim any excess tape and fold the raw ends under or sew a small fabric tab over them to prevent fraying. If you are using the tape in a lined bag, the ends will be hidden inside the lining. A fabric tab also gives you something to hold when opening the zipper.
