Bear in mind that at 11 years old you are still growing. Having a tattoo now means as you grow your skin also grows and the result could be that your tat looks faded or even distorted. A great idea to remember your Dad but I'd wait a few years. You can get temporary tattoos which can last for a week or a month.Could be worth checking out first. This would also give you a chance to get used to it and also try out different designs.
You can't have a tattoo when your 11 evan if your guardian gives you permission. You have to be at least 16.
Wait sweetie and save your money and pay for a good tattoo from a reputable artist. Good ones cost a bundle and most really good ones won't even touch you for under $200.00 so remember when you decide to get one to research artists all over for the best and be prepared for it to cost you a pretty penny. If you get one in a few years and pay like $50 for it you will regret it later.
I understand that this tattoo will mean a lot to you and I respect you for making such a good choice at such a young age. Most children your age will want some boys name or a flower or something. I give you props for choosing something that actually has meaning to you. I apologize for your loss as well. If I were you though I'd wait until you were 18. You'll be legal and more mature. And just like User Unclederek said You're young and still growing...wait a while until you get the tattoo.And research the best artist just don't settle for someone just because they provide cheap prices. Remember when you get a tattoo you really get what you pay for. Hope all this helps.
You are not too young for a tattoo if your parent or guardian gives you permission,the real question is can you stand the pain..
18 you can do what you want, but wait till you're like 19 or 20
