My mission was to make earrings from a piece of black leather, decorative black ribbons and black safety pins that I got as a gift from my friends. The shape just happened without planning. Now when it is ready I have been searching from different sources the symbol which the earring represents. First I searched for wheel (no hit) then for moon/sun (no hit) BUT I looked at the earring more closely and I am sure it is a horseshoe. For good luck and protection. And safety pins to firmly hold things together.
