Info and Diagrams
I made this origami T-Rex when I was actually designing my Velociraptor. I couldn’t decide between the flat head and the 3D head, so I made both versions.
I recommend using a paper that holds the creases very well or wetfolding. But it can be done with regular origami paper too. Leave the model inside a book for a while (before shaping) or use clothespins to let the creases set.
