Now, flip your fabric over so the wrong side faces up. Place your zipper face-down over the cut, with its teeth lined up perfectly under that slash. Pin or clip it in place. This is like holding a book open while you glue a page—you need it to be still.
Sew a rectangle around the cut, going about a quarter-inch from the edge of the slash. This is called a stay-stitch box. It sounds fancy, but it’s just a frame that holds everything together. Sew slow, lift the presser foot, and pivot at the corners like you’re parallel parking.
Once that rectangle is sewn, here comes the big reveal: snip the ends of your cut diagonally into the corners of the box. Don’t cut the stitches! This lets you push the fabric through the hole, like turning a sweater inside out. Now push the zipper through the resulting slit.
Voilà. You now have a zipper installed in a hole. It looks like a messy miracle, but it’s real.

Finishing the Edges
Flip your project to the right side. Tug the fabric so it lies flat around the zipper. Iron it if you’re the type of person who irons things. Then, topstitch a neat rectangle around the entire zipper, about a quarter-inch from the teeth. This locks everything down and makes it look professional.
Think of topstitching as the cherry on top. It’s not just structural; it’s decorative. You’re telling the zipper, “You live here now, and you look great.” A contrasting thread color can make your pocket pop like a neon sign.
Pro tip: Use a zipper foot for this final pass if you have one. If not, just align your needle close to the teeth. It’s like parking a car—you’ll get the hang of it after one or two tries.
