At some point in your sewing practice, you will have to insert a zipper, and it doesn’t have to be that scary. (I have to keep telling myself that and keep improving that skill!) Let’s learn how to sew a zipper!
Match up the raw edge of the fabric with the outer edge of the zipper tape. The outside fabric should be facing the right side of the zipper. Pin it carefully.
Put a zipper foot in your sewing machine. Move the needle to the side closest to your zipper. Sew the three layers together, getting as close to the zipper teeth as possible.
