Sleeves are not easily covered unless you have a long sleeved shirt on. Some people choose to stop their sleeve before their watch so that people in the workforce can’t see it, even when they shake someone’s hand. Other people choose to extend the work past their wrists and onto their hands. It’s a personal preference and different for every individual.
If you know you eventually want a sleeve, or if you’re going full-sleeve right out the gate, then Gualteros recommends starting at the shoulder. From there, you’ll work your way down the arm. “If someone came to me and let me do whatever I wanted, I’d start from the top with something that fits the body,” he says. “Something that doesn’t look like a sticker on the arm, then bring it down and fill it in.” Alternatively, he notes that some of his customers and fellow artists prefer to start at the wrist and work their way up, but on the same principle: By starting on one end, you aren’t guessing where to place everything else. Instead, you’re moving up or down the sleeve and filling it in with some kind of order.
The American Academy of Dermatology distinguishes five types of tattoos: traumatic tattoos, also called "natural tattoos", that result from injuries, especially asphalt from road injuries or pencil lead; amateur tattoos; professional tattoos, both via traditional methods and modern tattoo machines; cosmetic tattoos, also known as "permanent makeup"; and medical tattoos.
