Tiny origami

I was working from home today to be present for an energy audit. Rachel came home and wanted to do crafts. We cut some newsprint into squares of decreasing sizes. I folded a small one into a crane. Then, after Rachel left, I succumbed to the compulsion to attempt the tiny one. I used my thumbnail to make creases. It was difficult, but apparently not impossible. I'm not confident of the dimensions, but I think it began as a three quarters of an inch square, approximately.
