Arboralea is worked in the round up to the armholes, then split for the front and back. The neck is shaped by simply binding off sts on one row and then each side of the front is continued straight up to the shoulders. The collar is worked as a separate rectangle and sew in after. The sleeves are also worked in the round up to the underarm and then the cap is shape and set in.
The sample shown was knit in Osprey by Quince and Co., shade Leek.
Gauge: 15 sts and 21 rows = 4" in Stockinette Stitch.
