Make sure that the top of your invisible zip (i.e. the plastic tip at the top of the zipper) sits just past the ¼“ seam allowance at the waist. Pin in place, making sure that the fabric is sitting right side up, facing you with the seam open. The zipper must be face down on the fabric. Make sure to line up the zipper coil edge with the seam allowance crease. Place pins parallel to the zipper teeth. Note: the zipper tape is always narrower than the seam allowance.
