I don’t mind at all, I learned to make these back in high-school and I know i have seen it online. I will look up a link, but it does require square paper. Once you fold the basic form, its just a matter of assembling the pieces.
6 pieces makes a cube
12 makes a stellated Octahedron
30 makes the stellated Icosahedron above
I understand there is a form made form 90 pieces, but I haven’t attempted that.
