I've only just seen this thread. Wow, I'm amazed by how many wonderful pieces everyone has!
I started when I was 18 and I've currently got 8.
3 fairy and flower related ones on my back, a tribal & tiger lily tramp stamp and a chinese dragon on one shoulder blade. A 'real' dragon over my left hip and a small celtic symbol on the top of my right thigh/hip.
My latest is still in progress (my 40th birthday present from my hubby), that's a half sleeve foo dog on my right arm. I've got 3 more sessions booked for that and then it will hopefully be finished. Going for a lotus flower on the underside.
After that I might end up going for a half sleeve on the other arm. It's true what they say, they're addictive!
