Basically, I was just going for a consistent repeating pattern of those teardrop shapes.
This uses a standard triangle grid.
The points on the teardrops are created using rabbit ear sink folds. Rabbit ear sink folds are probably my least favorite of all the typical tessellation folding techniques. But we do what we must for our art.
I only employed a 32 pleat gird. This would look really fantastic on a bigger grid.
