## Origami Tessellation Basics: Triangle Grid

### how

I really forgot how to make a hexagon from a square. could you maybe make a video showing how to?

### Thanks for videos

Dear Sara,

I saw many origami tessellations photos on flicker of Eric Gjerde and many more origami artist. I wanted to learn there techniques for quite sometimes. I searched on a web a lot but couldn't able to move any were.

Couple of weeks before I just decided, I want to do at least one origami tessellation on that day. And first think came in to my mind is to check happyfolding web site. And I found these videos. I was very happy at that movement. Thank you.

Following is link to my picasa web album, in which I made three origami tessellation using triangle twist, square twist and hexagon twist. These are not at all properly made tessellations (may not very interesting for others) but these are my first attempt and first step of origami tessellation.

I would also like to thank Prof. Eric Gjerde for his "Tessellation basic booklet.

Thanks again for videos.

Best regards,
Archana.

### Well done

You've got some very cleanly folded models there. Congratulations! I think it's also really good that you are experimenting with the basic techniques to get some nice patterns. That's probably what's so intriguing about tessellations, too. You can easily make your own pattern by just combining different basics. Of course, the art lies in finding interesting combinations and the less obvious ones.

### Origami Tessellations

Dear Sara

I am 16 years old and have been doing origami for about a year now, but I am not that great at it. I mean, the hardest thing I have managed perfectly would be a seal on a rock from a single sheet of brown/white paper, thanks to a book of mine. (Unfortunately as of yet I don't have a flickr stream to show you.) However, your videos have been the greatest help, thanks to the considerable amount of detail and effort you manage to put in.

The reason for my leaving a comment here is to request you to do a few more tessellation videos, as I find them the most visual appealing, not taking into consideration insanely complex models like those of Robert J.Lang or Satoshi Kamiya (I hope that is his correct name). I was hoping you could make a video of something more from Eric Gjerde's work, as the book is most probably not available in India.

Anyway, I would still like to thank you for your videos.

Best regards,
Varun

### Tessellation video

I do plan to make more tessellation videos. However, the next couple of videos I want to make won't be on tessellations. So I fear the next tessellation video won't be up until a couple more months. You can try to fold some from crease pattern, if you like, but it's of course a bigger challenge. Eric Gjerde has quite a few crease patterns on his website, though: http://www.origamite...

can you do a video on the open back hex twist or rabbait ear sink

### Accuracy

Hello Sara,

First, I just wanted to express my thanks to all that you've done here. I'm personally a huge fan of your work, and can safely say that >50% of all the models I've ever folded have come from either your videos, or from books that I've purchased after first seeing designs that you folded from them. Keep the the tremendous work!!

I also wanted to ask you for a bit of advice. I'm having some struggles with the accuracy of my triangle grids. I can create one of 16 divisions no problem, but as soon as I go for a 32-grid, my accuracy goes out the window, no matter how long and deliberate I fold it. This is especially annoying on the trickier models in Eric Gjerde's book. Imagine folding Aztec Twist on a considerably-off triangle grid! How do you fold your larger division grids with such beautiful precision? I'm in awe.
Thanks so much!
~ Christoph

### Some ideas

Hm, not sure, I've found it no harder to fold accurate grids with higher divisions. I haven't done any more than 64 divisions, fyi. This is what might help:
For small divisions I fold edge to edge, creating lots of pleats. When I work with higher numbers of divisions, I make a couple of pleats, unfold those and then start the next set of pleats. Like this there are never too many layers of paper on top of each other, which makes working precisely harder. Paper choice is also important. I find it much easier to work precisely with translucent paper, because rather than aligning edges, I can indeed align creases. The translucent paper I have has quite prominent creases, and the translucency thus allows me to see the creases through a layer of paper.
Another reference might be not to necessarily align edges for higher divisions, but really using the existing grid lines. And the order in which you crease is also important. I first make a full grid of 8 (all three directions), then expand it to 16, then to 32, etc. If you first do all divisions for one direction, then the paper will have a significantly different size in that direction. Getting the other directions done precisely is then harder. Always remember that the paper size changes when you add creases. Adding lots of creases will show how significant those changes are when they add up.

Hope this helps a bit,

-- Sara

### Thanks!

Thanks for such a detailed reply! I think one of the major issues with my grids of that I folded 32 divisions all in one direction, then started from scratch on the other side. I can see how this would change the paper size in one direction. I was also making huge amounts of pleats back and forth on the larger divisions, which by the end, only about half lined up properly =)

I will most definitely implement these fixes on my next tessellation. Thanks again for your great help!
