I came up with a simple modular, primarily to fulfill a commission for an umbrella. If you use 4 units (instead of the 3 for the brolly) , it produces a star shape. My good friend Francis Ow tells me that it’s called “The Star of Lakshmi”, used in Hinduism to symbolize Ashtalakshmi, the eight forms of wealth.

On the right are 2 clues to the construction, see if you can figure it out (the 2 short creases are used to lock it together)…

If you turn the umbrella upside down, it makes a nice flower as well 😉
