My pattern calls for the length of my sweater to be 34cm before shaping the armhole. I made mine 40cm so now that I am working the front I would do the same but it is telling me to BO 24sts at center front edge for the neckband. It says when the piece measures 30cm so that means I would add the 6cm on here too right? I would start the neckband at 36cm and the armhole shaping at 40cm right? :??
