Seamless Octahedron

[Intermediate] How to fold a clean, sturdy, octahedron with no creases on the faces, from just one square of paper, no cutting! You can use a sheet of origami paper or printer paper cut square. Relative to other origami octahedrons this one is easy and since it is seamless it is extra clean looking! It’s also an efficient use of paper since it’s just from one sheet! If you can attach a thread to it using a needle then it will make a nice origami ornament. It also is a great project for a geometry class!
