The sleeves and body will be split on round 85. I need to figure out how each part will be worked.
Whichever of the sleeves or body I work first, I’ll do a provisional cast-on with waste yarn for the underarm stitches. Then when I want to do the other part, I’ll remove the PCO and capture those live sts on the needle along with that part’s held sts from the yoke. Note that because I’ll have one less stitch when I remove the PCO, I’ll do a yarnover right in the middle, to add the stitch on which I’ll do the same afterthought phony seams as on the U-Neck. {add link to that post}
