Pinwheel Sweater (Adult)
This pattern could be easily adapted to fit any size. As shown, the sweater fits small, medium and large. It can also be worn two ways; as pictured above, with the longer part of the circle below the sleeves, for a long, dressy look, or with the shorter part of the circle below the sleeves for a more casual short jacket look.
Version for children is also available as a separate free pattern from elann.com.
