This is really quite an ingenious pattern. First, it starts with a provisional cast on and the bottom lace is knit side-to-side, then the bottom front edging is knit onto each side to turn the corner. Then, stitches are picked up along the bottom trim and the main body of the piece is knit, including the front edging, up to the armholes. After splitting for the armholes and knitting the fronts and back separately, they are rejoined and there is raglan shaping, and then the front edging is continued up and knit onto the back stitches to form the collar; then a little trim on the armholes and it's done! Completely, totally seamless. I highly recommend the pattern--though if I were to do it over, I might modify the lace pattern a bit to make it symmetrical. The only modification I made this time around is to add one lace repeat to the body for a tiny bit of extra length.
I used the Cascade 220 Heathers in Alki Beach I had left over from my Creature Comforts Cardi. I'm regretting that choice now because the other color of Cascade 220 I had in my stash was my first choice, but I wasn't sure I had enough--I would have. Hindsight is 20/20 and all that. Oh well, maybe I will have to make another one! It's a very wearable style in the Southern California fall weather. I still have some Alki Beach left, too. Maybe some mitts?
