5 Note that the back neck facing can be made from the same fabric as the body of the jacket, or you can use a contrasting fabric for effect. With wrong side facing, working along the base and side of the piece, fold in 1cm and press. With right sides facing, place the back neck facing to the back neck section of the jacket and pin in place. Using a straight machine stitch, sew along the upper section that will run along the back of the neck. Trim the seam allowance, clipping the curve for a smooth finish.
