how do i stick a sign on someone's back without them noticing?

You can use a piece of thin cloth like a T-shirt or a poster that has the sign printed on it. Tie the cloth around their back so that it covers the area of their back that you want the sign to be visible. It might also help to use double-sided tape or a small piece of adhesive to make sure the sign sticks securely.
