Crafty Intentions patterns are such crochet witchcraft. Making a monster to be a hook and tool holder and this leg is made in multiple parts but no sewing anywhere.
You make three toes, use the fourth to join, then work to the ankle, create a new opening using chain stitches then close off the joint and finish off. Reattach to make a new tube and repeat those elbow steps, then attach one final time for the thigh.
