This cardigan is knitted from the bottom up.
The body is worked back and forth up to the armhole, where the work is set aside while the sleeves are knitted. The sleeves are worked in the round.
The pieces are then joined, and the yoke is worked with raglan decreases, made as centred decreases in the main colour.
Stitches are picked up along both fronts for the button bands, and finally, stitches are picked up along the neckline and the neckband is worked.
