Just made this origami model
.
It is
Skella Alpha Kusudama (taken from the book
Zen Origami) made from 30 square pieces of paper. It is designed by
Maria Sinayskaya, who has a lot of other cool origami designs on her website.
The paper I used isn't optimal, as it is rather coarse, but it is quite sturdy and thus supports the model rather well.
I made a similar model out of smaller, more delicate (=more expensive) paper earlier today, but I left it at the coffee shop as a gift...
