From the pattern:
This shawl/vest is super easy and knitted in a K1 twist, P1 rib. It is a rectangle with two slits for the armholes but creates a very pleasant, interesting shape when worn. Knitted in a worsted weight yarn for hand dying, this shawl can be made in its natural color or dyed in any color or color combination you create.
