Here’s a photo of my most recent origami project. It’s an icosa-dodecahedron, constructed from units folded from 60 rectangular sheets of paper. (Yes, no glue was used.) The design is from Unit Polyhedron Origami by Tomoko Fuse. It’s about 20cm across.

The paper came from this package available at Paper Jade.
is very coool
Can you show us a photo of the base shape used in the origami?
Yes, but give me a couple of days to look it up, fold it, and photograph it. It looks like a strip of three trianges with tabs on the end, I think. Two of the triangles are visible surfaces; the third slides into a pocket in the adjacent unit. The tabs get trapped in the convex edges of adjacent units so it all locks itself together.
I really like this origami unit. Putting together complex constructions like this can be fun and challenging. I have a site that shows some other units that have less pieces.
