This pattern in made in a few parts. A large rectangle is made to fit the object it will go around. The toes are crocheted, stuffed, then sewn to the rectangle. The rectangle portion is sewn around a pillar or post. The whole foot requires a remnant of yarn. This pattern requires the ability to make single and half double crochets.
Though this bears a resemblance to the monster feet in Moore and Prain’s book “Yarn Bombing: The Art of Crochet and Knit Graffiti”, the pattern is entirely different.
