Origami Spiky Ball

I learned this recently, and it has become an instant favorite. Why? It only requires 12 units (as opposed to 30, 60, or 90…or 100+), and the results are fantastic for the relatively little time spent! Happy folding! 🙂

P.S. You can also make a larger model with 24 units or 54 units.
P.P.S. There’s nothing wrong with using some glue to make the units stay together permanently. 🙂
