Help with painting scripture on bedroom ceiling?

I'm wanting to paint 1 Corinthians 13 on our bedroom ceiling in some sort of spiral design. I just want it to be pretty and look professional. I'm weary about doing the spiral design thought because I just don't know how I would get it just right... but I can't think of any other design that would look right.. I think it would look funny just written straight across on the ceiling. Anyone have any ideas or tips on doing this?
