Construction
This seamless vest is worked mostly in the round in stockinette stitch from the bottom up. You will first work the bottom section of the vest in the round, before splitting at the underarm point to work the back panel flat, followed by the front panel where you will shape the V-neck. You will join the shoulder seams to create the neck hole and armholes using the Three Needle Bind Off method. The neck and sleeve trims are worked in the round by picking up stitches along the neck hole/armhole edges. The lemon is then worked onto the front of the vest in Duplicate stitch.
