The body of the sweater is knit bottom up in the round, then the body is split to knit the front and back, after that the shoulders are connected using a three needle bind off. Then, the sleeves are picked up around the armhole and knit down. I used one strand of dk and one strand of mohair held together, so it is really cozy, or you could use one strand of worsted. This pattern has been tech edited and test knitted.
