Someone asked me how the movement of the Ningyo-Joruri puppet head that I made during Nori Sawa’s masterclass a few years ago worked , so I’ve drawn a diagram on my iPad to illustrate the mechanism. It makes more sense if you look at in context with my photoset from the class, and perhaps with the original blog post.
