they were selling them in all the Dominos in South Korea last October. I didn't try one so I don't even know what the star topping was made of.

The hexagram here is one of the very limited times you'll see it alone in India. Typically Moghul architecture will use the hexagram as part of a tessellation.

This is a copper enameled star. Copper enameling is the process of melting powdered glass on copper. To see more of my work visit www.feingoldjewelry.etsy.com. For more information, check out my profile.

I like meeting designs of our national emblem in materials that are new to me, such as this original design.

My daughter's 14 year old friend (who is not jewish btw) was wearing them with a lime green mini and bronze ballet flats and a mohawk. she looked super cute.
I saw Star of David earings and necklaces, neckties and nose-rings, hats and pins, but this is the first time I see it on leggings.

Ethiopian Orders

Ethiopian Order of Solomon's Seal is a cross inside a Solomon’s seal. It is suspended from a green ribbon. It was established by Emperor John IV in 1874.
“The Most Exalted order of The Queen of Sheba”, 1922, Awarded by Empress Zawditu to ladies, is also a cross inside a Solomon’s seal.

Strongest Versus Weakest

ATR commented jewishanswers.org:

The star is reaching out in all directions and anchored by a central point, I would surmise to be the Torah. Each of the six lines of the star is attached to another, and stands upon a foundation. The whole star system is very powerfully supported in its design.
You might contrast this with a swastika, which also has six lines, and without support or anchor. The Mogen Dovid is the strongest and most supportive thing you can do with six lines. The swastika is the weakest.
