Well, tbh, there’s nothing specifically significant about them. The stars on my hip I got first (2007), and I’ve always had a thing for stars and the night-time and celestial objects, because they’re universal, because they’re something people dream about and look to for inspiration, and because to me they looked kinda sexy. ^_^ The one on my shoulder I got in 2009, and I decided to have the moon included there, too.
To me, they’re sort of timeless, too, and indeed, I love them a little bit more every day I see them. I’m thinking about a third tattoo, something small on the inside of my forearm, but I’m not sure what it’ll be yet.
