This is a tessellation that I had been considering for a while and thought that it would be too much work to actually do it.  I looked at my diagram and just thought it would be too hard.  Eventually, I worked up the nerve to try it and as it turns out, it wasn't nearly as difficult as I thought it would be.  As with any flagstone tessellation it was 90% preparation and only 10% actual folding. There are lots and lots of creases to create before you go about getting the paper to fall into place.  Some very advanced folders don't pre-crease, but I just find it makes the whole process frustration-free. All the papers that I've used, which admittedly aren't that many different kinds, out and out refuse to do anything meaningful without pre-creasing.  It's a pretty straightforward pattern to figure out. Rhombuses with triangles touching all four sides.  My crease pattern to fold this tessellation is included below. I didn't draw the back side triangles...

  It's been a while since I've done this kind of collapse style origami tessellation . So, here is a new one at alas. The idea for this involved tucking triangles and rhombuses into a central rhombus. It creates a kind of jagged pattern that can be repeated.  In my case, I repeated it using open back hexagons and long parallelograms.  What shapes land up and which ones land down is purely a personal choice. You can spend quite a bit of time just fiddling around with which way everything should go. I know that I did.  Me, I like it when the triangles are up and the other shapes tuck into them. Your mileage may differ.  The back side of the tessellation is basically just the inverse of the front. Such is the case with straight up collapses such as this.  It's a somewhat tricky tessellation to fold. A lot of unwilling tucks with which to contend. Whenever I do one like this, I just let the paper go in whatever direction feels easiest. Then, when I get every...

 This tessellation I really like a lot. My idea started out as doing something with long parallelograms connected to each of the four edges of a rhombus. As seen above. Originally, I thought that I would just repeat the pattern, but upon drawing it out, I realized it couldn't be repeated straight up.  A few extra shapes thrown in the mix and I was able to completed the central idea.  I added some open back hexagons on the front. On the back there are large and small triangles.  This is a slightly difficult tessellation . Having some larger shapes on both sides helps make it not too difficult.  My diagram is included below.  This is my first post for January 2026 Origami Tessellations . Although technically, I created it on December 26, 2025

 I've been sorely lax in uploading new folds, but I'm slowly trying to catch up on that. This tessellation is one that I don't really recall. According to Google, I uploaded the photos on November 15, 2025. So, probably created a day or 2 earlier.  I don't do a lot of fully twist based original origami tessellations , but in this case, I did. It's always nice to mix things up once in a while.  It appears to be an open back hexagon with open back triangles twisting off of it. From there, I'm not exactly sure what I did.  It looks like I might've done some small triangle twists a little ways off from the larger ones on the reverse side.  What I do remember, is that it was conceived from the back side - the picture below. But upon seeing the completed tessellation, I decided what had originally be the back should instead be the front.  It's a pretty simple tessellation compared to my usual ideas, but interesting nonetheless.  If I took a picture of my c...

 In this origami tessellation I was looking to use a different shape than usual. I don't recall if I ever used this particular shape before, but I think I have seen it used by others, but not in this exact configuration.  The structure is very simple. It only consists of two shapes. The one seen on the front and long parallelograms on the back.  The main shape is a rectangle with clipped corners, creating six edges all together. The long edges cross two pleats, while the short edges bisect one.  The parallelograms are two pleats on their long sides. and connected by cross cuts.  It was a fairly easy to fold tessellation . The larger shapes that it utilizes saw to that.  My crease pattern is included below.  I did this one a back in mid November, but it's posted under: December 2025 origami tessellations .. 

This is a pretty basic original tessellation as far as the structure goes. However, it's somewhat difficult to actually fold it.  Everything is tucked very close together and on top of each other.  The idea for it was collapsing some triangles and then repeating.  On the opposite side are many small hex twists nestling not so very neatly.  If you look at the crease pattern you can see that it's mostly a standard flower collapse, but I've added the triangles into it to confuse things.  I actually folded this back in November, but have only just gotten around to posting it.  Filed under: December 2025 Origami Tessellations

 This is one of those simple origami tessellations that backlights really well.  It almost looks three dimensional, but it is actually a flat fold.  I was looking through my photos searching for the diagram I used to create this, but I wasn't able to find it.  I don't remember it 100%, but from looking at it, I believe it's open back hexagons with small natural trapezoids tucked into them. That's a starting point I tend to favor.  From there, it seems to be triangle twists connected to the trapezoids.  It will have to be unfolded so that I can upload a proper crease pattern. I'm curious to remember just how I did it.  That will come soon.  The reverse side is very plain. This further reinforces the theory that it is a layered type design that is constructed using the pattern mentioned before. When you fold open back hexagons in that way, you essentially just wind up with multiple layers of very little consequence on their own. The trick is, what ...

 This is a pretty nifty little flagstone tessellation that I recently thought up and folded.  Basically, it's a series of long parallelograms connected in a recurring wave formation.  The same pattern can be done with rhombuses. And has been done, by others and myself. But it has a different, cooler look when you use the longer shapes.  It's an intricate looking design that uses a fairly simple pattern.  On the back side, it's all triangle twists.  Most flagstone tessellations don't back light very well, but this one does.  It's a moderately difficult tessellation . If only because it requires so many creases.  I have a crease pattern. Just need to add it.  Although, it's not at all difficult to discern how to fold it. 

 I don't really recall how I came up with this particular tessellation . Essentially, it's negative space triangles connected by long, hexagonally terminated arms.  The triangle shapes are created by twisting parallelograms around a small hex twist on the other side. Or, from the opposite perspective, they are open back triangle twists tucked closely into the hexes.  Just how I decided to add the connectors that I used to repeat the pattern, is anyone's guess.  Taking a good look at it, I kind of wish that I'd used shorter runs and kept things closer together. But, you know, hind sight is like that.  I've had some mishaps recently with trying to space shapes too close together. So, as a reult, I was probably being overly cautious.  The opposite side winds up like looking like a very easy flagstone, except the hexagons are on the wrong side.  It was pretty easy to fold. I did it with ordinary paper. No problem.  I think that I located the correct ...

 This is a rare white paper tessellation. I have this large pile of 28 lb printer paper that I got to fold tessellations. Then, I later discovered tant paper and the printer paper has mostly gone unused.  But, to be fair, it backlights wonderfully. However, it is very susceptible to moisture. So, pros and cons.  Under the right circumstance, it's a great paper with which to fold origami tessellations . The trick is to weigh the complexity of the design, the relative humidity and how the finished fold will look using it.  A big part of the process of creating tessellations for me, is deciding what paper to use. It seems simple, but it's not. And it has a big impact on your finished model.  This tessellation is a series of alternating rhombuses and triangles. They are connected at a greater distance than I typically utilize. Thus, creating different shapes in the gaps.  When I looked at the picture of the finished fold it reminded me of that board game that ...

 This is a nice straightforward design that uses the flagstone origami style.  It consists of open back hexagons surrounded by trapezoids.  To repeat the pattern is simple. Just connect the short sides of the trapezoids.  Some large triangle take up the gaps between.  There are also small triangle on the backside. Quite typical for a tessellation of this kind.  It's one of your easier to fold flagstone tessellations thanks to the large triangles that leave more space between the shapes.  Crease pattern below.  Filed under: November 2025 Origami Tessellations

 This difficult tessellation is sets of three interlocking triangle twists twisting around layered open back hexagons. I've used this starting point several times. It can yield some interesting patterns. My triple decker triangle sandwiches tessellation for one. There have been others, which I can't recall at the moment.  Essentially, you fold small, natural trapezoids off of open back hexagons. This creates the layers. From there you can create any number of configurations.  In the case of this particular tessellation , I did sets of triple triangles. I'm definitely a fan of interlocking triangle twists. I'm always on the hunt for any way I can find to come up with new designs which incorporate them..  The back side gives a clearer view of what's actually happening with the hexagons. The little points sticking out from them are the trapezoids partially tucked under their edges.  I was looking through my photos for the crease pattern and didn't find it....
