That is what I have done as well. The worst thing I have seen people do is get one on vacation, especially at the beginning of a trip. Now you have a wound you have to care for and keep out of the sun and water. Way to ruin your trip.
@Tundra Tiger My buffalo tattoo was 2 appointments, so that took over a month since you have to let the first session heal before doing the second. Your appointments are going to be at least 2 weeks apart. People with full sleeves or full back pieces often take multiple years, especially if they only do it in winter. How much you can do in one session is going to depend on your artist, the style, your pain tolerance and how your skin reacts. A good artist can tell you what you should expect.
Just don't cry
