The third of the models that I tried was the Origami Striped Sonobe, assembled into an Octahedron, from 12 modules. The assembly is, of course, different from the Large Cube assembly from my last post. 

The Octahedron is formed from pyramids, in rings of 4 pyramids. I love this assembly - it is easy but at the same time, looks quite complex. And the striped sonobe modules give it a nice touch. 

The colour combination is the same as my previous models - deep blue, light blue and yellow. The size remains the same - 3-inch squares. The resulting octahedron is about 3.5 cms (~1.4 inches). It fits nicely into the palm of my hand! A super-cute model :)

As a gift for a friend, I had again folded the origami Patterned Icosahedron, created by Meenakshi Mukerji. I had previously folded it during the Christmas season. And enjoyed making it.

So this time, I decided to go with a pink and lavender duo-coloured paper, a favourite of my friend's, which resulted in a very pleasing modular origami. And I also went with smer unit sizes than my previous attempt and still was able to fold and assemble without any problems.

The Origami Patterned Icosahedron has been on my to-do list for quite some time now. This pretty icosahedron is designed by the amazing Meenakshi Mukerji. The icosahedron is assembled using 30 modules and looks best with dual coloured paper. The same module can be assembled using 12 units to form the Patterned Octahedron.

The modules are pretty easy to fold and are folded from a rectangle in ratio 1:2 i.e., a square cut into two. I had used a green-red combination in the hopes of adding it to my Christmas Tree. But I get the impression that this looks more like a strawberry than an icosahedron, courtesy of the black dots on the red, I guess 😄😄 Nevertheless, it is a good modular to fold.

The assembly is, by modular origami standards, fairly easy. I would still recommend plenty of paper clips and an equal amount of patience when assembling this one!

Did you know that the Platonic Solids were named after the Greek philosopher Plato? He believed that these were the fundamental components of nature and associated fire to the tetrahedron, earth to the cube, air to the octahedron, water to the icosahedron and the element cosmos to the dodecahedron.

As the name suggests, the Octahedron has got 8 sides, each of them equilateral triangles. I had thought that folding it would be more difficult than the Cube, but surprisingly, I found it easier to fold this! It is completely folded as a 2-dimensional model, till the last step where it is inflated to form the 3-dimensional Octahedron. The dual of the Octahedron is the Cube.
