Review of the paper used: 

Some time ago I started this tessellation, and didn't have time to finish it. I'd only done the grid and the first rabbit-ear triangle sink fold. I had a hard time figuring out how to do that one. Today I decided to complete it, and thankfully I immediately got how to do the rabbit-ear triangle sink fold, and after some fiddling this is the result. The pictures shows the model from both sides. Given the name, I'd say the right one is the front view, and also the side I think I prefer. But with tessellations you can always decide which side you like best.

Paper: hexagon from a 19.5cm square of transparent paper (side length of hexagon: 10.5cm)
Model: hexagon with a side length of 5.5cm


Rabbit-ear triangle sink fold?
That almost sounds like Inside reverse fold when I first started origami.
Cool Awsome model though.

I completely agree that it's a rather unfortunate name for the fold, but I was at quite a loss about what to call it. It's a triangle sink, of sorts, and a rabbit ear maneuver as well, and thusly for lack of a better name I called it what it is. Hopefully the readers will forgive me (in time)... :)

It's a very handy folding technique for tessellations, and works with shapes besides 60 degree angles. I've done some fun stuff with octagons using this same method.

There's a model later on in the book that combines hex twists and this technique to make a more complicated result, which I think shows the value of tessellations quite well - you can combine things together to make bigger, better designs, the only limit is your own ability to fold and your ingenuity.

Thanks for sharing this, Sara!


try backlighting the origami stacked triangles

The method that is used to create the triangles is actually the same method that Eric used for his 2.1 version star.

Are there no videos for this tessellation?
Or you didnt contact the designer?
I would like a video soon on this.

I might do a video on this in the future, but I'm not sure. Please remember that I usually make instructions for one video a month, so in terms of internet time I am anything but fast.

I now how you made this. I already made Spead-Hex, Four and Five, the Waterbomb (that was 1 day before you made a video) and Star Puff. And I dont got the book!!!
How many divisios did you use here? Then I can make this model to!

I love your videos Sara!!!

Looking at the picture, I'll have to guess 32 divisions.

i seen others this is one of the best ive seen nice chose of paper..... the right looks like icecubes and the left looks like iceblocks well thats what i think

i just wanted to say that about it looking like ice

This is an awesome model! thank you for sharing
