Inner Arm Tattoo opinions. . . .?

That area is too small for the amount of script you want. In order for script to look good for a long time it needs to be done fairly large. Otherwise, if done too small, it could start to blur together within a matter of months and then no one would be able to read it. I do like the quote, but pick a bigger area to get it done so that it can be done right; after all it is going to be with you for life! I suggest maybe the rib area or the back.
