It begins with your standard small hex based rhombus flower at the center. It then proceeds to repeat the rhombuses in a linear pattern off of the center starting points. I really like it.
It was a pretty standard flagstone fold. Patience is definitely required.
If you use a hexagon as your starting shape the edges are difficult. As with other flagstones the fold does not naturally fit that shape.
It's a pattern that fits very nicely in a smaller 32 pleat grid.
The end result is pretty impressive.
Kudos to whomever first conceived of it.
