This versatile vest is created with "Rhythm Superwash" yarn from Jojoland. The piece is knit in modular fashion with a series of swirly hexagons that are knit together as you work. The sides are not seamed, so it fits like a poncho. Turn it sideways so that the back covers one arm and the front the other, and you have a completely different look. One size fits most and requires 15 balls.
