On both your dress videos (2147 and 2444) you show how to staystitch the neck area of the bodice/yolk 1/2″ from the edge from shoulder to shoulder in a continuous stitch. Then yesterday I was on the Simplicity website and they do it a little differently: they start at one shoulder and stitch to the center of the neck; then they repeat on the opposite side. When looking at the pattern directions, it seems to show this too.
I know the first time I tried stay-stitching the neck from shoulder to shoulder I got some puckering in the fabric. I spent a little time adjusting the thread tension, omitted a tack stitch at either end and could smooth any residual pucker in the fabric. But when I do this one side at a time, there seems to be no puckering.
Is there an advantage to doing it the way you show?
