How long, What shop, under who, and what city? Feel free to elaborate, especially if you ended up getting mentored heavily at a second shop after your start. For example, if you started at home, but then worked in a shop under a solid mentor, include that.
This is important. Describe what you want from your time at a new shop. Are you traveling? Looking for mentorship? Moving to a new city? Wanting to expand your network? Need a short term hustle? Tell your prospective employer what out of your tattoo experience and in their shop or city. This can make a big difference in if you are selected.
