Chum's Pullover is knit in bulky yarn, making relatively short work of a man-sized garment. The piece would look great with a pair of jeans, battered and old or crisp and sleek. It would also pair well with a pop of colour like red denim, if that's the way you roll.
The sweater is worked in the round from the bottom to the underarm, then the left front, right front (including placket) and back are worked individually and joined at the shoulders with Kitchener stitch. The set-in sleeves are worked flat from the cuff up and then seamed and attached to the body of the sweater. The neck flap and high neckline are finished with a crocheted edge to give the piece a nice, clean look.
The sample shown in the picture is worn with zero ease, and that is how the pattern is written. For a little extra room, I recommend knitting the next size up.
