Here’s my tuppence worth:
If you are ‘just’ thinking about it don’t bother. You really need to think it through. It’s going be to be there the rest of your life (laser removal or cover up pending). Do some research, surf the web, there are millions of tatts out there. Find what you like the look of then develop it.
I thought about getting a tattoo for about, oh, 30 years but didn’t really see/think of anything until I stumbled across a Dr Woo one that I liked. I then did a trawl of the local tatt parlour websites/Facebook pages until I found someone I felt I could trust and went to speak to them. We then developed a design together until I was happy with it. I then put my deposit down and waited then, at the last minute, I decided I wanted a part change in design then got it inked. It could only go in one place. And I love it, turned out better than I had hoped. And when I showed my 86 yo old mum (bless her, she died two weeks ago) she said “ooooo, l like that! I didn’t think I was going to but I do!”
I’m now planning my next one. I know the basis, just got to work out exactly what/how I want it done. It will mark the passing of my mum and dad but will only be decipherable to a few people.
