tie (something) up in a bow

1. Literally, to tie two pieces of cloth or string together so that they form a bow. This excess material ties up in a bow, right? I'm terrible at wrapping gifts—will you tie this up in a bow for me?

2. To take care of, finish, or resolve something fully and completely, especially in a way that is satisfying or pleasing. OK, yes, I like those corny movies that tie everything up in a bow at the end. I hate when there are loose ends! We need every detail tied up in a bow before we make our pitch to the board, got it?
