I only have 2 thus far, both located above my weak ankles to provide extra protection.
On the right is the Mercury symbol with a crescent moon in it's head. Mercury rules Gemini, my sun sign, & my moon is in Cancer.
On the left is the Aquarius symbol, representing my husband & my daughter.
Next I plan to get the symbol for Gemini on my arm (the area of the body Gemini rules), followed by 4 crescent moons on the other side (representing the 4 members of my immediate family). The final design will be a pentacle on the back of my neck, totalling 5, reflective of Mercury & the five pointed pentacle (symbolizing mind over matter).
As you can guess, it's a very spiritual experience for me.
Change how you see, not how you look.
