I have the book power sewing step by step. I’m doing neck stabilising as per page 135. Step 6 says since you already trimed the neckline, sew a 6mm seam allowance . The new seamline ends up just inside the line of stitching for the stabilizer. Won’t that mean that the stabilising stitching will show on the right side of garment. Will be greatful for help soon.
P.S. I put this question as a comment on the lycra sewing topic so I hope the answer doesn't get doubled up.
