Prunille: I have yet to see LdL

, so I'm not sure how she has the ballet sweater in there, but I quickly perused my IK pattern for you, and here is a bit of the sleeves instructions: I think you could just keep extending the existing sleeves until they measure 4", then there is 1 dec at both sides of center underarm (ssk, k2tog)-work 5 rnds even. repeat 6 rows 4 times (this is pretty much the same for all sizes), work straight until sleeves measure 15". Then there are a few k1f&b increases to shape the cuff and that's it

.
onemorehour- your sweater is gorgeous! I haven't liked the shaping in the center until I saw yours. Thanks for the inspiration!
