that is the LAST thing you should do. if someone comes in my shop applying for an apprenticeship and starts by telling me how many piercings they’ve done already with no training, i have a strict rule to say no. if you start out without respecting how serious this job is, i cant teach you otherwise. find your favorite local shop, make friends with the staff (head piercer especially) and be a patron regularly. get lots of piercings done and tip well. give the piercer a reason to remember you.
