Hi everyone, I'm celebrating my 70th birthday later this month with my first tattoo and I'm curious whether the design is too detailed to hold up over time (10-15 years...I'm trying to be optimistic 😃). Right now, the one I am trying out using temporary tattoo paper looks good at about 6" long on my forearm. But I'd like your feedback on how large it will actually need to be to hold up over the next (hopefully) 15 years. I welcome any advise or comments. .
