Abby of NCIS has 9 tattoos what are they and where are they?

I know of 5 out of 9 I am putting together a holloween costume of her character.|||Let's see, there's the spider web and the large cross, the infinity symbol on her right forearm, the 3 triangles on her left wrist, the two angel and demon stick figures on her shoulder blades, one alluded to on her ankle (but I don't know what it is), and she told Carson that the others are "hidden."
