A neckband works because it is shorter than the neckline and pulls the edge in. Cut it the same length and the neckline gapes; the entire method is about that difference.
Cut the band across the stretch, so the greater stretch runs around the neck. Ribbing cut the wrong way will not go over a head.
Length: start at about 85 per cent of the neckline measurement for a soft rib, slightly more for a firm one. Always test with a ring of scrap around your head before cutting the real one — a band that does not fit over the head is the commonest mistake.
Width: twice the finished width plus two seam allowances, because the band is folded double.
Join the band into a ring with a small seam, then fold it in half lengthwise, wrong sides together, and press the fold lightly.
Quarter both. Mark the band and the neckline into four equal parts with clips — centre front, centre back, and the two midpoints — and match them. This distributes the stretch evenly, which is what stops the band being tight in one place and loose in another.
Sew with the band uppermost, stretching only the band to meet the neckline between the clips, never stretching the garment. Use a narrow zigzag, a lightning stitch or an overlocker.
Press the seam towards the garment and topstitch it down if you want it to sit flat.
Questions people actually ask
Can I use jersey instead of ribbing?
Yes, but it recovers less well, so cut it a little shorter and expect the neckline to relax over time. Ribbing exists because it springs back.
My neckband is wavy.
The garment was stretched as well as the band. Quarter both, and pull only the band while the neckline lies flat under the needle.
