From the designer: Upper body of cardigan is worked side to side, including wide reversible rib front edge/collar (which can be folded back); stitches are bound off and then cast on to create the armholes, and then stitches are picked up around the armholes, and the sleeves are knitted down to the cuff (the sleeves are NOT knitted separately and then sewn in, as stated on the photo page in the magazine). Finally, stitches are picked up along the lower edge and knitted down to form the wide ribbed hem.

VK directions for sleeve cap short row shaping are very brief: Here is a more detailed description of the process.

For a general visual, if the top of the armhole is at 12 o’clock, then the short rows start at around 4 o’clock (RS) and 8 o’clock (WS). On each row you will go one st further, until you reach the bottom center of the armhole. (I realize the armhole is in the shape of a rectangle, but luckily the fabric is flexible, and practically speaking it will end up in more of an oval shape in the finished garment.)

Altogether there are 78 (82) sleeve sts, including a panel of 9 (11) sts in moss st at the top and at the bottom of the armhole, and you start the sleeve rounds immediately after the bottom moss st panel. You start the short rows after working 63 (65) sts of the first rnd, at which point the sts remaining before the bottom center of the armhole are: 2 of the double braided cable, 4 in ladder st, and 4 (5) in moss st, with an additional st at the bottom center. (The above sts add up to 74 (77) instead of 78 (82) sts because there is still the rest of the bottom moss st panel-- 4 (5) sts-- before the start of the rnd.) Since you go 1 st further on each short row, you therefore will do 10 (11) short rows alternating RS and WS, and then one more to wrap the last st at the center bottom armhole. Then you will turn and work the WS until you reach the 2nd to last wrapped st, pick up and work it together with wrap, and then turn for the last time to the RS, work around to the bottom center, work that final wrapped st, and continue in rnds working from the RS from then on.

There should be 21 (23) short rows in total, 11 (12) on the RS and 10 (11) on the WS.

(To be honest, it won’t make much difference if you don’t wrap that last st, instead doing your last W/T from the WS, then turning and working from the RS in rounds, picking up the last 2 wraps as you go. Just keep track of what pattern row you are on; the sleeve shaping decreases are best done on even-numbered pattern rows.)
