im done knitting this (have yet to block, or put the buttons/closures on it) and for the people who had questions, i had the same. i knitted the extra small for a friend and was might freaked out bout the set up lace section because it wasnt even. but the instructions were fine, the 159 or something was the number without the 3sts in the beg and end (6 altogether) and even tho it wasn't intuitively even, everything worked out just fine. i hope this makes sense? anyways pics below. i used cotton fleece double stranded and did the cropped version.
