You’re going to knit the sts on the right front holder starting at the very edge of the neckline. This is the right edge of the held sts. If the holder is turned around so that the opening is facing the wrong way, slip the sts off to another needle so that you’re knitting heading towards the sleeve.
When you finish knitting them, the yarn should be coming off the right needle and ready to start picking up sts on the right front neck edge. Just pick up the sts along this edge as shown in the video (some directions call this “pick up and knit” but it’s all the same)…You don’t have to knit these sts again until you have all the neckline sts on the needle.
When you’ve picked up sts the yarn should again be at the tip of the right needle ready to knit the held sts for the back neck. Re-orient these sts if you need to.
