My daughter will be baptized next week and we are mexican catholics need suggestions on the bolo?

usually the bolo which is where we throw money at the children to pick up during the party well i will not be having a party but was thinking of giving the children the money after the mass instead like in a little gift bag or envelope but need some suggestions on how to do it in a unique way. If I put it in an envelope what type of envelope what should it say should i put a card inside or if I put it in a little gift bag should I put a card inside of it or tie a ribbon on it can someone give me some suggestions or maybe you have been to a baptism were they did something like that.
