Q. How do you insert an invisible zipper?

Answer

Here are the steps:While flattening the zipper with the iron's tip use the fingers to uncurl the teeth. Apply this on both sides.Flip the clothing inside out so that the right side is facing the user.Invert the zipper so the teeth are touching the cloth. Due to the thinness of the tape we were able to leave a quarter of an inch of fabric beyond the zipper.Attach the zip with pins. In this photo as in all others depicting the sewing of an invisible zipper the zipper pull is positioned such that the teeth are facing down.The coil of the zipper needs to be positioned in the left foot groove.
