The differences between each of them are the angles and the shape of the base (square, triangle...).
These foldings are time consuming and require a lot of precision, and a bit of dexterity as well ;-)
What is interesting is that they are 3D foldings and "pop up" in a way, but can be flatten as well to admire the shapes.
As usual, I can sell some of them if any interest you. But I won't sell some as those ones are a pain to fold and I am not up to make them again. Feel free to ask if a folding catches your attention!
