In this video I’m going to show you how to do a hexagon twist. which is one of the basic tessellation techniques used in orgami. You need to start on a triangle grid, and I advise you to use at least eight divisions. If you don’t know how to do a triangle grid, do check one of my other videos. First, locate a point on the grid and then the hexagon that surrounds this grid. It will consist of exactly six triangles that all meet in the point located. Now make mountain folds on that hexagon by just pinching on the grid, not creating any new creases but just going along existing ones. All you need to do is make them into mountain folds, like so. Then make mountain folds on each of these points of the hexagon that go straight to that point so that the third crease will enclose 120 degrees on each side, or 2 triangles on each side. You will have to do six of these, because the hexagon has six such points. Like so. Now, fold the hexagon in half along one of the creases; for example, along this one. Like so. Now, you’re going to look at one side. Here you have a mountain fold, and right next to it there is a crease, and you want to make that a valley fold. So just pinch that to make it a valley fold. Then, the next one, just going counterclockwise there’s again, one mountain fold we’ve prepared, and again, parallel to that mountain fold, we’re going to pinch a valley fold on the grid and do that again and again, and once you’re through – once you’ve done one whole rotation you have a couple of valley folds in place — six. Now pinch that hexagon in half again, I’m trying to really fold it in half completely this time so it’s flat and then go along the valley folds you’ve prepared. This one, and that one and this one, and that one. And then for the last one, you actually have to open the hexagon and then you’ll see you’ve done a twist. You’ve done a hexagon twist. Let’s unfold that again, and can you see how it twisted open? If you want to do it a different way, you can just pinch all of these and you get a twist that’s clockwise, so we’ve folded that one over, and that one over and that one over, and that one … ..this one, and finally, that one. and going along the creases which collapse all of this you can see that you can’t quite collapse it in the center and that’s where you have to twist so this whole hexagon twists around — can you see that happening? Right there? Then you can actually flatten all the creases and you’ve got a flat model again. But I like doing it the other way which is folding the hexagon in half and then the twist happens automatically. Just by folding open the whole structure. This makes it easier to make a very neat twist.
