If you prefer, sew the basting stitches by hand. Since the basting stitch lines are simply guidelines, you’re not actually sewing the fabric edges together. The lines just help you position the zipper so you sew it in straight.
The flat side of the zipper should be laying flat on the right side of your garment. If the zipper is bent or curled, lay it flat on an ironing board. Heat your iron to the synthetic setting and run it over the zipper tape to smooth it.
Don’t pin the right side of the zipper at this point. You’ll attach the right-side zipper after you’ve finished sewing the left side in place.
You’ll see 2 grooves on the invisible zipper foot and your sewing needle will stitch in between them.
The invisible zipper foot glides along the zipper teeth as you sew, so this should only take a few seconds.
Avoid sewing the bottom tape end to the fabric of the garment or your stitches will be visible. If you can see the basting stitches when you turn your garment right-side-out, pull the basting stitches out.
Remember that the fabric side next to the zipper teeth is called the zipper tape. Turning your garment inside-out lets you see where everything lines up.
Fold the pattern-side of the lining over towards the wrong side.
This gives your garment straight, professional-looking seams.
Ensure that you don’t pin the liner over the teeth or your zipper will snag.
Sew with the same thread that you used to sew the zipper to the garment. Make your stitches about 1⁄8 inch (0. 32 cm) long, so they’re short and strong.
