Roses Tessllation

-
A lot of origami tessellations employ equilateral triangles in their design. In some they are the focal point. In others they help to bridge the gap between other shapes.

This tessellation uses right triangles instead.

It starts off typically with a central small hexagon. Instead of a classic hex twist, it uses an offset twist. This is how the triangles are formed.

An offset hex twist is simply folding a small hex twist as you would an open back hexagonal twist. Instead of using the natural axes of the grid, you bisect them.

Whichever direction the central hex goes, the next repetition goes opposite. If your grid were big enough to allow for more repetitions I imagine you would need to keep alternating.

I used the mountain and valley folds at the ends of the triangles to determine which way the second generation would flow.

There are some additional offset folds to make everything play nicely together. But nothing very complicated.

All in all, it was not a difficult fold.

I've included below a very basic crease pattern for a single module.

Infinite Triangles Origami Tessellation

This is just a flash idea I had. There was no planning involved. No inspiration. I just started folding and followed the lure of the creases in the paper.  Upon seeing the finished result, It kind of reminds me of Robin Scholz's Triphilia tessellation, but the construction is definitely different and I was not thinking of that as I was crafting it. The similarity is that you can arrange the layering of the triangles into different patterns of your choice.  I went looking and discovered  I had folded this a few years ago and called it Triangle Temptations . I didn't realize this until after I'd completed this model.  Apparently, according to my original post, I'd seen someone else fold it on flickr and recreated it.  This happens sometimes. You hit on an idea and it's something you've done and forgotten. They linger in the back of your brain and come forward unexpectedly.  That previous version differed from this one slightly, in that it used double sized cross g

Micro Rhombus Stars Origami Tessellation

 This tessellation is micro rhombus star twists. I'm pretty sure I've seen this done with larger size rhombuses, but not with ones this size. They are the smallest natural rhombuses of the triangle grid.  The center is achieved by collapsing a small hexagon.  On the other side there are small hex twists and open back triangle twists.  Since the shapes are rather small, it's a little bit difficult to fold.  It's probably more of a cool weather tessellation. Humidity does the paper no favors on such small designs. But the ideas come when they do.  Reverse view and crease pattern images follow.

What If Caviar Could Talk Variant

 This origami tessellation is a variant of one by Arseniy K. He named his 'What If Caviar Could Talk'. After I had solved his design, I decided that I wasn't up to  reproducing it exactly as he had folded his. Perhaps another time, in the future. So I changed things up a little to make it slightly less difficult.  Both designs have a foundation of open back hex twists with triangle twists around them, He used micro rhombuses between the repeats.  In my case, I used larger natural rhombuses instead.  Still a difficult fold to execute, but much less so.  It still required thick paper. I used tant folded into a 32 pleat triangle grid.  You can see from the photo of the reverse side how densely packed everything is.  It's a few layers deep. So be prepared to wrestle with that.  My crease pattern for this iteration is included at the end.  To fold his, sub out small natural rhombuses in place of my larger ones.
