Here is a recent origami project that I have completed. It is a sonobe variant by Meenakshi Mukerji in the form of an extruded dodecahedron. (That was a mouthful) It was a little confusing to figure our how to put it together, but with a little tenacity, I got it.
You will need to fold a total of 90 units. Start by making a pyramid and connect 5 pyramids to make a pentagon shape. Connect pentagon shapes on each face of the pentagon, so you will get 5 pentagons surrounding one (see diagram below). It will make more sense in building. Where three pentagons connect, there will be 6 pyramid units. When finished, you will have 12 pentagon units connected into a sphere.
