^^r u sure is a catholic 1, cos im C of E & ive got it on my arm (dam thats a pretty big fuck up) but i think the catholic cross is a different design and a bit more detailed,
(4 people who live in the uk) roy keane's cross on his arm is the catholic 1
but 4 the tattoo, jus go in with the booklet or a picture of it and say u want that 1, if there anygood they'll draw it on the spot,,thats what i did, u dont need to know the exact name of it
but its a pretty popular cross so theyll prob already have it in one of there design catologues there
