This beautiful modular Origami model, the Star Icosahedron, was designed by the talented Origami artist Evan Zodl from the United States. The diagram to this model can be found in the Origami USA Convention 2014 magazine.

Paper and Supplies
For the Star Icosahedron you will need 20 sheets of rectangular paper. The rectangular paper has to have a ratio of 1:1.1547 or greater, as you will need to fold and cut a Hexagon from it. The Hexagon will be your starting shape, from which you will fold your modules. You can use single colored paper like Kraft paper or even copy paper, as only one side shows. If you plan to use Kami paper, remember to start with the white side up. In the video I have used blue copy paper. I think this kind of paper works nicely, as it is already in it’s rectangular starting shape (A4) and it is reasonably thin for folding and creasing several layers. The downside is that little bends from handling and folding will show in it’s final design. You also will find it to be less forgiving when assembling your model. It will be slightly to soft when you try to insert flaps into pockets.
If you use A4 size paper (11.69 in x 8.27 in/29.7 cm x 21 cm), your finished model will be about 5.9 in or 15 cm high. You can also use US Letter size, 8.5 in x 11 in.
Besides the paper you will need a pencil, scissors or ruler and craft knife.
There are 3 main stages to complete the Star Icosahedron:
1st Stage – Folding and Cutting your Rectangle into a Hexagon
2nd Stage – Folding
3rd Stage – Assembly
The folding of your Hexagon to it’s final shape is not too tricky. It is actually quite fun to fold the modules. You will like the two collapses, which should not be too difficult if you watch the video. Normally I tend to use my nails for creasing, but as this is quite a big job with medium thick paper, I improvise with a blunt kind of knife. You can use a bone folder if you have one, or improvise like me.
I estimate that it takes about 15 minutes to finish one module from it’s starting shape as a rectangle to it’s final shape. I tend to fold my modules over several days, so I don’t get fed up from too much folding.
To connect the units together is not too demanding. You first start to connect 5 modules together, which will form a vertex. Whenever you insert the fifth part into a vertex, you will have to be patient. This can be a bit tricky and annoying, but it will slide into it’s place eventually. I did not use paper clips or clothespins during my assembly. Once you have one vertex constructed, you go on all around it and add modules to make up more vertices. All together you will have 12 vertices, which will make up your Star Icosahedron model. I did not use any glue during any stage of my model, and your final Star Icosahedron will hold neatly together like this.
This model can make other shapes than the Icosahedron. If you fold 4 units, you can make a Tetrahedron. It is slightly more difficult to assemble than the Icosahedron as it is a connection of 3 instead of 5. This makes it more tight and more difficult to slide the last part into place. Besides that you could try also a Octahedron which will require 8 units. Try to be creative, and see with what shapes you will come up.
I loved folding the Star Icosahedron, as it is slightly more complex and entertaining than other kusudama style models. The two collapses are fun and provide a change in the normal folding – creasing pattern. This model is not too demanding and is well suited for intermediates.
