Since tattoos are of such an incredibly personal nature, it is very common for people to seek a custom tattoo. After all, a standard, run of the mill tattoo is not likely to reflect the deep meaning that you want your tattoo to have. Naturally, only the best tattoo artists can render a personal, custom tattoo to your standards and without errors and mistakes that maul the whole piece. You will need to consider who will draw the original piece - maybe you are a good artist yourself and already have something prepared and, maybe not. If not, you might need to have the tattoo artist design the whole tattoo for you. If that happens to be the case, you definitely want to examine the tattoo artists' portfolios to see which style will work the best for what you want. Other things you will want to discuss with the tattoo shop include coloring for the piece, the size of the piece you have in mind, and how much time it will take.
Color, style, size - that is the fun stuff about getting a custom tattoo - but, you also want to make sure that the tattoo shop uses healthful and clean processes in their work. For the needles, single-use disposable needles are by far the best and safest choice; however a good sanitizing system is adequate as well. It is also a good idea that your tattoo artist wears latex gloves while doing your tattoo - accidents can happen, even with the best tattoo artists, and it is always better safe than sorry (for both of you) when it comes to bodily fluids like blood.
If you take care when choosing a tattoo shop for your next tattoo, your tattoo will go on without a hitch and you will never have to worry about needing tattoo removal!
