In honor of Socktober, this and ALL of my sock designs are 10-30% off during October! See this post for details.
A bough is a primary branch of a tree, and something about the branching design of this stitch pattern made me think of that. These are a great unisex, lace sock that are worked top-down for two sizes (64-st and 72-st). The pattern includes both written and charted instructions.
