How do you write "Welcome Home Sara" in Arabic?

My cousin is currently on a trip to Germany. It's her first trip over seas and she is w/out her fam(also a first), so we want to give her a big surprise welcome when she gets home. She is half Italian and half Lebanese and I am full Italian, which is why I can't write in Arabic myself. Anyways, I am in charge of the cake, and since Sara is starting to learn Arabic, I know she would love it if I could get this on a cake. Please HELP!! (:
