Well, I survived the night....
Took about 3.5hrs. Didn't hurt as much as I thought it would...but it sore now.
The tattoo was to coverup one I had when I was 15 in a local dodgy tattoo shop. I was a bit of a muppet at the time and had my (now very very ex) gf's name on it. Needless to say when I recently got engaged it was top of the conditions list
Here is the old tatt
...now you've stopped laughing..
You can probably see remnants of tweety left, that's not the tattoists fault, it was mine for wanting a tribal\celtic design. Even saying that he's done a fantastic job and actually you can't see any of the old tattoo unless you get real close. Bearing in mind it's on my right thigh, next to my nuts, I doubt many people will be getting that close
Many thanks to TF for recomending an excellent tattoist and a top bloke!
