Design by Little Monkeys Crochet.
This polar bear hat is for free in the baby size. If you want larger sizes you can get them for a small price on Ravelry. The polar bear has a 3D look, including the ears. The braids and edging make this ideal for women, but in the right colors, this might work for men as well.
The pattern calls for a worsted weight and a bulky fur-like yarn and an I and an H crochet hook.
