A few things I try to follow when getting a new tattoo -
* Don't drink alcohol for 24 hours before or 24 hours after you make it.
* See to it that you are well rested and well fed when you get it done.
* Keep it clean and put antiseptic salve on it when ever needed for at least the first four weeks.
* Keep it from sunlight and don't go swimming / bathing for at least the first four weeks.
* Make damn sure that the design you are getting is what YOU really want and can live with for the rest of your life.
* If you want to fill it in less often, keep your desings all black and no colours.
Anyways, that's what I have learned about thsi art so far
Most of them sort of say: Don't do it at a festival
