Aces High Origami Flagstone
This is a new flagstone tessellation that I recently created. It has a couple of interesting sets within it. It has some diamonds created by four rhombuses. It also has pyramids created by six rhombuses flowing around a central triangle. The center is a classic six triangle hex shape. Although the design doesn't repeat on my 32 pleat grid, it is repeatable with more divisions. This is a difficult tessellation , although, if you're familiar with flagstones it becomes much less so. See the crease pattern for how to fold it.
