12 Grade the seam allowances by trimming the jacket neckline seam allowance to 3/8"
(1 cm) and the facing seam allowance to 1/4" (6 mm). Clip into the neckline seam allowance every 1/2" (1.3 cm), clipping up to, but not through, the stitches. Clipping allows the facing to turn smoothly to the inside and lie flat.
