Overlock or serge the armhole, turn the armhole hem allowance inside and pin in place, take care not to twist, once in place sew the turnback down with a top stitch.

With right sides facing sew the two angled ends of the neckband together, clip carefully into the “V” and press the seam open.
Turn the band to the right side and press in half lengthways. Clip any “V” excess seams allowance away. Understitch along the seam line of the outer two raw edges of the band to hold it in place then lightly press.
Pin the neckband to the neck, matching the “V” of the neckband to the “V” of the body, carefully clip into the “V” on the body making sure you don’t clip more than the seam allowance. This will ensure a sharp “V”.
Start sewing at the centre front “V”, firstly sew the “V” either side.
Once the “V” is perfect then sew the rest of the neckband to the neck of the body. Neaten the seam with a serger/overlocker and press the seam toward the body, lightly steam the neckband with the iron so it will sit nice and flat.
