The instructions you have are slightly different from what you may have seen in the short row video. Sometimes, as in the video, you complete the next row to the end after the w&t. Your pattern has several rows with w&t and then a row where you pick up the wraps. It's not so unusual, just different from the videos.
I know you posted the example of 16 shoulder sts (16-26-16sts) but that wasn't your size. How many sts do you actually have for the shoulders?
