I think this is standard stuff, but I'm confused anyway! For the body pieces of this cartigan, I'm supposed to bind off three stitches for arm-hole shaping and then continue with the pattern. For seaming, it says to place markers a certain distance down from the shoulder seams and then to seam-on the sleeve between the markers. I'm confused because these markers will be an inch or so above the 3-stitch-BO that was for armhole shaping. So what does that BO have to do with the armhole, if the sleeve is sewn on higher up?
Thanks in advance for words of wisdom!
