Essentially there are two different ways to get a sleeve tattoo done. The first way and probably the most common way is that a person starts by giving individual tattoos. For example they like and a pair of lucky dice or a nice pinup girl tattoo on the forearm that later add a tribal tattoothe shoulder. Over time these individual tattoos will cover larger and larger parts of the arm eventually forming a sleeve tattoo. The second when the people go about getting sleeve tattoo is to come up with the full sleeve tattoo design first and then have the tattoo done over multiple sessions. Really there is no right way to go about getting sleeve tattoo design however many tattoo artists will tell you if you want to end up with a full sleeve tattoo that it is better to design first as one piece. These type of tattoos to look more coherent and cohesive at their design.
