How do you have the hexagon with water sac?

I need to make the petal leaf, in one form with different variation inside. Like most water to the least water in the petal.


As a first guess I tried something along a simple rectangle. I’m sure there are other ways but I can’t seem to achieve this with simple math tools :frowning:
Maybe you could try to Sporph that result on what seems to be a closed sweep you have here ?
