Description by Karen Boykin:

The Mia Shrug pattern contains instructions for three versions: one knit flat using twisted purl, one knit flat using the standard knit and purl stitches, and one knit partially in the round without any seaming.

Yardage needed will vary by your size and by the finishing treatments you choose. The above figures are guidelines only. Be sure to check your gauge and measurements, and plan accordingly.
