The origami wedge cube is a visually captivating modular origami that I had wanted to fold for some time now. This model, designed by Miyuki Kawamura, is assembled from 20 modules - 8 of the corner modules and 12 of the pyramid structures.

I found it a fun model to fold and assemble. Neither the folding nor the assembly is too complicated. Assembly is by sliding a pocket into a flap. It is assembled without any glue and holds together very well.

Loved the colour combination, chosen by Little Miss. The brown and the pink contrast very well, I thought and the final model is really eye-catching!

The Christmas Tree Ball or Origami Icosidodecahedron is a modular origami made from 20 squares of paper. This is, in fact, Tung Ken Lam's jitterbug units assembled into an icosidodecahedron. The jitterbug units are themselves quite easy to make. They can also be assembled without glue, though I prefer gluing the modules together.

I had this pretty wrapper paper that was great for this model. But it looks equally good in solid colours. Thin origami paper might not hold the shape well.
