I've been waiting to start this project until Interweave published the correction. Here's the text, finally:
When working the Diamond chart, work the inc round as written in the pattern. On "work even" rounds, work as follows: Cont in patt as established, [work to next m, sl m, k1, work to next m, sl m] 2 times. (In other words, on the "work even" rounds, knit the first sleeve stitch after the marker.)
After beginning the Right Cable and Left Cable charts, work the Inc round as follows: Inc rnd: Cont in patt as established, [k1f&b, work to 1 st before next m, k1f&b, sl m, M1p (see Glossary, page 123), work to next m, M1p, sl m] 2 times--8 sts inc’d. (In other words, use the M1p increase on the sleeves rather than k1f&b.)
Hope this helps.
