So, I spent the better part of yesterday knitting the first third of a sleeve, ripping, calculating, and trying again. There is just no way my Queensland Aran can be forced attractively into a Twigs and Leaves cardigan. Not with my knitting ability anyway. The yarn weight is just too heavy.
As much as I love the pattern, I love the yarn more. Using that yarn right now is my priority, so the pattern is being shelved. I'm back to the proverbial drawing board.
