After completing the flat version of Jack-o-Lantern, I was searching for one that would not lie flat, a 3D version. And found this beautiful one, created by Tomohiro Tachi.
The CP for folding it is available on Flikr! I haven’t done much folding using CP, but that wasn’t an issue since Jo Nakashima has posted a detailed, clear and very useful tutorial on Youtube for folding the model.
