I decided that Calvin needed to be Calvin for at least one Halloween. So therefore I needed to find or make him a Hobbes. So naturally I crocheted him. I found a free pattern online, though I did make a few modifications (he needed whiskers and I added more white to his face. Something I should have done while creating the head but it was an afterthought.)
Here is the pattern: Hobbes Crochet Pattern
Here is Hobbes
Calvin has been carrying him around saying "I love it"
