The Billet-Doux (Billy-Do) Beanie is sweet, fun and a little bit whimsical. Texture is added in two ways by using contrasting yarn weights and fibers, along with garter ridges in-between, taking a classic striped beanie from basic to beau. The fit is oh-so-slightly relaxed, it has aesthetic crown shaping and features a double thick, folded stockinette brim that creates the coziest, fluffiest lining of Suri Alpaca silk yarn.
