So I can't decide lol idk if I should do my hair or get another tattoo. It'll be small and simple like this and be located between my color bone and breast. Not sure which side but how much do you think an artist would charge for something like this? I'm no longer breastfeeding but I just want something to always be there as a reminder that my boobs provided and helped my baby get through his first month of life and get him through jaundice in the first month. If you was an artist how much would you charge?
