Thank you so much! The instructions just before this read, "Continuing in established Stripe pat, bind off at arm edge...." then what I previously posted. Yes, it is a cardigan, very cute, but my skills are a bit rusty, and I had not encountered this type of instruction before.
I have e-mailed the company which published the pattern also, and will post their reply when I receive it.
I also just realized that I neglected to mention that this shaping of armhole is on the right front of the sweater. The back shaping had me binding off 4 sts at beg of 2 rows, then 3 sts at beginning of 2 rows and then 2 sts at beg of 2 rows. Will your way match that when the back and fronts are connected? Thank you!
