Critical instructions at the end of this section are missing! After the last line (Short Row 8), please add:
Knit back to marker, then work 2" in St st, k2tog on last 2 sts of final rnd.
Concentric Circles
PU sts are off by 1.
2nd Circle: ...pick up and knit 86 more sts (87 total)....
3rd Circle: ...pick up and knit 64 more sts (65 total)...
4th Circle: ...pick up and knit 42 more sts (43 total)...
and at the center: ...pick up and knit 20 more sts (21 total).
When you k2tog across the rnd after that last section, your final st will be a K st, bringing you back to 11 sts.
