This hat pattern is done from the bottom up with a knitted cuff, crocheted body, and knitted crown and is all done in one piece.

The right side features double columns when turned inside out to reveal the wrong side as feathered spines.

It takes two skeins of worsted weight yarn.

The pattern includes detailed instructions at the merging stages (where the knitting and crochet parts meet) and includes both left-handed and right-handed instructions.
