Okay, I hope I can explain this. I think it might be something on the order of a one block wonder made with hexagons. Those big triangles should measure the same on all three sides. I would take six of them and put them together, with the diamonds touching in the middle, to make a hexagon. The smaller right triangles on the right in the picture, I think these are half of the larger triangles - they are used on the ends of the rows to make a straight side. The long skinny triangle on the top could also be used on the ends. If you put 2 of the right triangles together, short ends together, it will be the same size as the skinny triangle on the top. If this sounds plausible, you could use the assembly instructions for a OBW to put it together. Looks like it might be interesting!! Ann
