The snail hand puppet is designed to fit a childs hand, but it also fits smaller adult hands. You should know how to knit in rounds and be familiar with increases/decreases.
You have to make an I-cord (how-to is described in the pattern instructions), graft and do short rows.
The instructions are illustrated with step-by-step photos to make it easy to follow.
