(From pattern intro):

Gibson is worked top down, with ¾-length sleeves, and the band/collar is worked from stitches picked up along the front and neck edges. It uses a worsted weight cotton/linen yarn. The body is worked straight, without waist shaping, so it is easily lengthened or shortened (just remember to buy extra yarn for a longer version). The lace-patterned sleeves, worked in the round, add interest to the simple silhouette; the every-other-row raglan increases are worked seamlessly into the lace.

The main lace pattern and sleeve raglan increases are given in chart form only.

HINT: If you need to join new yarn while working the band/collar, do it at the back of the neck-- the lower front edges roll and may also swing open during movement, exposing the wrong side, which makes it difficult to hide any woven-in ends.
