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
