From the North American Schachenmayr website:
It’s the best of both worlds. Simple crochet stitches are worked to create a stylish top to this hat, and then stitches are picked up and knit in a rib pattern to keep the hat snuggly on the head. The color combinations are endless using Boston and Boston Style.

This is a FREE pattern available to all visitors of the North American Schachenmayr website.
