In the tattoo industry, apprenticeships are not easy to come by. Typically, aspiring tattoo artists create portfolios of their work, either physically or digitally. Then they take these examples to tattoo shops to ask if anyone's looking for an apprentice or willing to mentor one. Once an experienced tattooist agrees, the apprenticeship structure depends on the mentor. Most partnerships last one to two years, with the first half focusing on drawing abilities and learning tattoo terminology and techniques. The second half involves actual tattoo work on human skin.
