Altering a Neckline on a Pattern
Gaping Neckline
Cut along a straight line from the neckline to the waist dart point and then through the center of the waist dart. Rotate to shorten the length of the neckline. The waist dart then widens. Re-draw seam-lines.
Large Neck
Lower the neckline, removing it from the front and back pattern pieces and altering any facing or collar pieces as necessary..
Small Neck
Re-draw and add extra to the front and back pattern neckline. Remember to add any extra to the facings and adjust the collar as needed.
