and I assume by double sewn you mean sew two lines of stitching

Double stitch. "Bar tack" is a machine term for it. Basically, I've found that it's better not to have the knot in a line of stitching be at the end of the line: rather, it's better if the knot is a few stitches back from the end of the stitch line. So what I was trying to say was, sew from the shoulder to the neck hole, but don't tie off there. Stitch back towards the shoulder about a half inch, or at least three or four stitches. That way, the neck hole has some reinforcement. If it still looks like it wants to tear there, then sew a couple of stitches, or three, maybe across the seam, so the stress doesn't hit the first line of stitching. If that doesn't make sense, PM me and I'll see if I can come up with a better way to explain.
