Speaking as a quasi-expert on tatooing (I'm a sailor) They are ADDICTING! Seriously, I have 12 tats and am contemplating more. If I had a digital camera I'd post them. Always personalize your tattoo, flash books are a very bad idea. Also, try to find a tattoo shop where the people there are into it for the art, not the paycheck. If a tattooist can't draw, he can't sling ink either, so always check that.
Something that no one has spoke of, safety. Before you get the tat, check the shop out. If the guy is using the same needle for each inkpot, there is a problem. Check sanitation, do they wipe the seats down afterwards (some tats can get bloody) all these things you want to look for. Skin infection is very very painful (Voice of experience talking) and is not something you want.
Now, on to my tats. The two that I'm am proud of are my half-sleeves that I have on each arm.
On the left arm I have a Death type figure in tattered robes, no feet showing. You cannot see his face but he clutches a rough looking scythe with the blade turned inwards. On the blade it reads Carpe Noctum (Not original, I know, but makes sense with the other one.)
On my right arm is a brunette (some of the little color I have in my tats) with delicate features wearing a simple, thin white dress that appears to be blowing slightly in the wind. The artist who I had sling my ink was good enough that he was able to fade the outline of her body onto my arm. Her feet are obscured by clouds. She is holding an open tome in front of her, you know, the big old-fashioned books. On the book it says Carpe Diam.
I designed both of the tats, but I didn't draw them.
Remind me again why I'm doing this?
