Yeah,being somebody’s practice canvas is tricky [that’s why I said uncle ’cause there’s always an uncle out there with a tattoo kit in the basement or whatever tongue emoticon ]
I was someone’s test subject once.
I helped a friend build a homemade tattoo gun out of a motor and needle. He tried it on himself, then on me. On my ankle. It hurt. It was micro-tiny but it worked.
Then on his own (once he ‘got’ the mechanics of it) he decided to take apart an electric shaver and use the motor to make a tattoo gun by himself.
It worked but… too powerful. Took him a few weeks to heal the skin gauging but it worked. The ink stayed.
After a while, he saved up and got a kit. Through the years, he got good, got jobs at various tattooo parlors and stuff.
I don’t have any tattoo now. It faded within a few months but it was cool helping somebody start their journey.
But if I wanted a regular tattoo, yeah, I’d make sure the guy/girl has done at least a FEW dozen tattoos first.
