@smiling.politely is on point. Tattooers can be pretty busy people (I don't know the person you are going to, but, for the sake of argument). A lot of the time they are not able to draw up your design until a day or two, or even the day of. Again, echoing what I said earlier, you might need to let go a tad. I'm very early in my career but I still typically don't work on a drawing until its time to do it, because its hard to spread energy around.
