I just wanted to let everyone know that there's an errata pdf now available from our website. You can click through on that link, or find it in the pattern description in the Current Issue section.
There were two significant errors in the sleeve cap area. The pdf addresses these. In short, the number of pairs of short rows ought to refer to individual W&Ts, not pairs, leading you to run out of stitches long before you execute all the turns that seem to be required. Work half as many pairs as it says and you'll be fine.
Again, apologies to all for the inconvenience and confusion.
