Halloween Ring

It's a bit early, but let's start practicing a model for Halloween! This is a variation of Nobuko's Puff Ring (https://origamiusa.org/thefold/article/nobukos-puff-ring-and-3-d-variations ). The assembly is the same as the original Puff Ring. How to convert the Puff Ring units into a pumpkin, a tomb stone, a cat and a bat will be shown in the class.
