How to sew a zipper

  1. Choose your zipper.

    Make sure that is the correct length for your garment.

  2. Open the zip and attach your zipper foot to your machine.

    If you are unsure how to change the foot over, be sure to refer to the manual. When attaching it, make sure the needle is on the side you are sewing, i.e. if the zip is to the left of your needle, the zipper foot should be inserted on the left.

  3. Baste shut the area you are sewing.

    Don’t panic, this will be removed later. Only baste the area the zipper will cover. Lay the zip over the seam and use a pin to mark the bottom. Baste to the pin. A standard stitch can be used to sew the rest of the seam closed.

  4. Iron the seam open.

    This needs to be done to the part you wish to insert the zipper.

  5. Line up your zipper.

    Make sure it is lined up correctly with the seam, and pin it in place.

  6. Sew the zip in place.

    Sew down one side, and across the bottom. Now switch the zipper foot to the other side and sew the other side of your zip to the top.

  7. Use a seam ripper.

    Use the seam ripper to remove your basting stitches.

  2. Make sure your zip is an invisible one.

    These have teeth that face to the back of the zip. Line it up with the inside of the seam you wish to sew it into.

  5. Check that your zip can be fastened.

    If not, you may have to unpick and restitch.
