I rejected the turtleneck as a concept when I was still a wee lass because there's nothing pleasant about wearing a tourniquet about the neck. But I gave the turtleneck another chance and this pattern is a winner because the neck is plenty roomy and, in a light jersey, unbulky.
This is the first pattern I've done a square shoulder adjustment on - that added to a forward shoulder/arm joint alteration. The top is too loose and stretchy to make a good critique of the new method, but I don't see any drag lines anyway.
Pattern: Burdastyle 9-2010-121.
Fabric: Cotton jersey with a little stretch from Mill End Textiles.
