When Joji announced the Fall KAL I couldn't resist the opportunity and cast-on as soon as we came back from vacation.
Changes: just the ribbing - I knit a twisted 1x1 rib instead of garter
Otherwise followed the pattern as written and didn't have any problems with the directions.
Sizing: I knit the smallest size (30/32) because my experience with this yarn tells me that it grows a bit with blocking and the lace pattern on this sweater is both in the front and back and so quite stretchy. I could've probably added some waist shaping if I wanted, but decided not to in the end.
Yarn: Madelinetosh DK in Tart (used a bit less than 4 skeins)
