One thing about tattoos, there is no eraser. No “delete” or “back” key. No “control + z” (keyboard command for undo). A tattoo is not an etch-a-sketch… you cannot shake it and start over. Romney has the patent on that.
Before getting a tattoo with any text of any type, it is highly recommended that a spell check is completed before the needle hits the skin. Google it. Grammar check it. If you and/or the artist’s English is not very strong, write it down and find someone whose English IS strong – neighbor, friend, teacher, librarian, convenience store clerk – and double/triple check the hell out of it. Have the paper with the CORRECT text right there next to the artist. Tic off each letter as the artist progresses. An ounce of prevention is worth a forever-lasting misspelled tattoo. When it comes to lettering, cover-ups just don’t do very well.
