- Set your sewing machine to a normal stitch length.
- Place the right side up and smooth the fabric and zipper.
- Starting at the top of the zipper, topstitch an even distance from the seam line, stopping with the needle down when you reach the straight pin. Tip Always watch a guide and not the needle when you are sewing. It is almost impossible to sew a straight line if your eyes are watching the needle. In this photo, my eye was watching the area with the arrow so I maintained an even distance the entire length of the zipper.
- At the bottom of the zipper, remove the straight pin and pivot.
- Sew perpendicular to the seam line, counting the number of stitches until you reach the seam line.
- Sew the same number of stitches on the other side of the seam line, stopping with the needle down.
- Pivot and sew the opposite side of the zipper, again keeping the topstitching an even distance from the seam line.
- Sew to the top of the zipper and back stitch in the top seam allowance, where the facing or waistband will be attached.
- Carefully remove the basting stitches that are holding the seam closed.
