Construction

This is top-down double hat. Inner and outer hat joined at ears and forehead level.

Continue to work inner and outer hat stitches in the round at the same time. When the piece reaches the level of the ears at back of the head, work each ear flap separately.

Finish the hat with 4 seams: at forehead, at back of the head and at bottom edge of the ears.
