Sharpening the Knives Flagstone

Sharpening the Knives Origami Tessellation

 This is an interesting hybrid flagstone tessellation that I recently designed and folded. 

It uses a few different techniques and patterns. It was pretty hard to actually fold. Some of that difficulty can be attributed to weather conditions and the paper being softer in warmer/more humid seasons. But it's also a tricky configuration to execute even under favorable circumstances. 

There was a good chunk of time while I was collapsing it that I was doubtful that I would be able to successfully complete it. Fortunately, it did work out. I was able to bring it to completion. Even if not quite as neatly as I would have liked. 

It starts out innocently. Just a common set of six triangles attached to an open back hexagon. 

Then I add a right triangles  and mirror image right triangles to the edges of the original center triangles. 

At that point the secondary pattern emerges where the regular triangles and right triangles can be twisted around an offset small hexagon. 

With that set fulfilled, the central set can repeat and so on and so forth.

I did take a photo of the crease pattern immediately after I finished the fold. However, it came out quite blurry. Pretty useless. I'll take another soon and add it. 

This is a difficult origami tessellation. As I recall, there were some unusual overlaps on the reverse side that made it particularly finicky.But if you have some experience with more challenging tessellations and are looking to advance your skills further, this might be a good place to do so.

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 cr...

Herringbone Tessellation

Messing around with rhombuses yielded this interesting pattern. It utilizes reverse rabbit ear folds to create triangular points which connect the running rows of rhombus twists. The triangles form in the spaces between the rhombuses. Then there are mirror triangles to facilitate the the next row.  It kinda looks and folds like a square grid tessellation even though it's done using a triangle grid.  It's a fairly easy fold.  I do have a crease pattern. Just need to take a pic and upload it. Update: photo of crease pattern added below.

Natural Rhombus Herringbone Tessellation

Image
This is in keeping with my exploration of non-hexagonal twists repeating. It's just a dizzying array of rhombuses all linked to one another. It employs an up/down repetition pattern. The rhombus shapes are different from traditional rhombus twists as they follow the natural grid lines. This crease pattern is a natural flow of the same single shape ad infinitum. It takes advantage of the natural folds of a triangle grid to create an easy to fold collapse that results in a complex structure of repetitions. It's difficult and a little confusing trying to get all the collapses to flow in the same direction. Especailly at the edges where the shapes get truncated. You could potentially alternate directions as well. Or come up with other patterns. The folds go forward or back at your discretion. I often find it frustrating to see a folded tessellation and no crease pattern to accompany it. Depending on how the photo was taken, the lighting and the clarity, it can so...
