This is an origami tessellation idea that I had a while back. Because it seemed so simple, I didn't rush to fold it. It languished for a while waiting for me to become interested.  On a day when I didn't have that much time, I decided to try it.  It's a very simple concept of large hexagons with natural triangles. I add small hexagons at the points of the triangles in order to repeat the pattern.  Some open triangle twists finish off the remaining space.  The diagram included below doesn't really fully illustrate the further finishing touches that I added to it.  Once I had the whole tessellation flattened I did small triangle twists with the corners of the large hexagons. This created kind of pseudo open back hexagons in their place. This led me to then fold their edges inwards, creating the final design.  It's hard to tell from my 32 pleat rendition, but the design is fully repeatable.  Even though it's a very simple concept, it wasn't easy at all ...
