This is a disaster waiting to happen. People who rush into tattoos often wind up with shit tattoos. First, three inches is too small, it will look like a scribble. Second, the simpler the tattoo, the better the artist you need because they have to be exact. You can’t walk into the first shop you see and get the first artist available.
Put on the brakes and think this through. And do your homework finding a good artist. Good artists usually have waiting lists, you can’t just walk in.
