People who perform/compose with looper pedals... how do you end a song?

Basically title. I can do good sounding stuff (instrumental guitar - like ambient, post-rock kinda) but I add layers on top of layers on top of layers, there's that nice crescendo, it sounds really full and loud and emotional - and then what? Just stop abruptly? That might work for one song, but not for all of them.

What do you do? Bend down and turn the loop volume down so it fades out? Can't think of anything lamer than that lol.

Any tips?
