Note--Errata: At the beginning of pattern, after you CO and knit 16”, and pattern tells you to CO 18 sts at beg of next 2 rows, this should be BOTH of your sleeves, not just the left. The actual pattern instructions were correct, just not my bit about a left sleeve. Corrected in new version.

This pattern calls for 1 skein each of the MC and CC, but you’ll have a good bit left over--possibly enough for another pair of socks. :)
