December Beanie

December Beanie is a simple and classic hat in stockinette stitch that can be made with or without a folded brim. It is worked using 1 strand of Merino + 2 strands of Soft Silk Mohair held together throughout. The hat is double-layered, making it extra warm, and the two strands of Soft Silk Mohair add extra softness and coziness.
December Beanie is worked in one piece from the top of the crown on the outer layer to the top of the crown on the inner layer while shaping both crowns with either increases or decreases. Afterwards, the hat is folded inside itself to make it double-layered.
The increases are worked as simple yarn overs that are worked through the back loop on the following round.
