Thanks for your reply!
As I wrote initially, the pattern is written to be worked flat, but I am knitting it in the round (bottom up).
check out how many sts are held or bound off for the underarms on the front and back
No stitches are held/bound off according to the pattern, which is why I'm confused :/
The pattern section marked "Armhole shaping" simply goes:
Work 2 sts tog at each end of the next 2 rows (128 sts).
Next comes the "Yoke shaping" section with decrease rounds.
So does that mean I just add in the sleeves without holding back sts? (Sounds strange?) And do I add them before or after the 2 armhole shaping rows?
Yes, I believe the extra rows in the back are for neck shaping, I'm not sure why there are fewer rows in the sleeves than in the front, though. But would I be able to accomplish these differences in the number of rows by using short rows?
