I got the crease pattern for this one from Daniel Kwan's flickr. It looked really complicated and difficult to fold, but it was actually pretty easy.
The ones I think will be easy are always hard and the one I think will be a struggle are usually a breeze. That's no one's fault, but my own, I suppose.
His is iso area. The design does not extend to the edges. But I'm a sucker for going all the way out to the edge.
It yields a really pretty result. Both the front and the back are quite nice.
It took no time to fold. It's a very straight forward concept. It artfully demonstrates the beauty in simplicity. .
It's perfect for a beginner just getting started on the concept of tessellations.
His original crease pattern is shown below.
