Yes, I think you should first know what you want and then spend your money on a quality design of your tattoo.. just google “tattoo ideas”.

Good luck!

Welcome to the forum, I’m also new…

Do you have a link to a picture of your tattoos?

As far as I know, a good translation for “the power of three” would be:
כוח השלושה
And the Trinity in Hebrew is:
השילוש הקדוש
But since any mistake would be kind of permanent, I would suggest you use a professional translator.
