I refolded my Therizinosaurus from a sheet of really thin unryu:
I don't recommend thin paper at all, make sure to use at least 40 or 50 gsm for this. It was really hard to shape, and it doesn't look very neat at all.
Here's my third attempt at my Therizinosaurus, this time going for as clean a result as possible.
It still needs some work in the body and legs, but it's a million times better than greenie up there. Folded from 30cm of chiri unryu.
I taught my girlfriend how to fold Kamiya's Coelophysis today. She hasnt folded anything in about 12 years, and the most complex thing she ever made before this was a traditional crane. Hers is the green one, mine is the white one.
