This tessellation is a very simple idea that I really can't believe I hadn't thought of before.  It's two classic configurations combined into one complete flagstone design .  The pattern alternates between six pointed rhombus stars and six triangles around a small hexagon. That's it. That's all there is to it.  My 32 pleat grid didn't allow for too many repeats, so I just tried to create clean edges. But it could keep going on a larger grid.  My original diagram that I used to start wasn't totally accurate, so I adjusted as I worked the fold. I will add an accurate crease pattern sometime soon.  It's a somewhat difficult tessellation to fold. Because all flagstones are sort of difficult. But it's nothing that can't be done with a little bit of patience.  Filed under: August 2025 Origami Tessellations
