I have wanted a wrist tattoo for a while, and I have 5 others.
I'm pretty happy with all my tattoos, I thought about them for a long time before going, but two I got when I was underage, so the workmanship disappoints me... especially on the one on my hip. He did such thick lines, and it's just... gross. The only way for me to fix it is to get a cover up, and I think that'll look worse on my hip.. but anywho.
I agree to really think about it, and try to draw it on for a while to make sure it's something you're gonna wanna see forever... or maybe in a different spot if that may not be the case. I love all my tattoos, but if I had to look at my "tramp stamp" (I was 15 when I got it.. cut me some slack!) everyday I'd go nuts.
I also cannot get a wrist tattoo after all, as well. I'm gonna be working in a hospital, and visible tattoos are not allowed
Although tattoos are widely way more acceptable now, there are still some places that don't allow them, so maybe look into that.
