How I organize my ideas

When I am trying to figure out either a storyline, a plot, or a particular character arc, I use post-it notes. I lay them out on a board or on my desk or something, and then I write down the scenarios or plots I am trying to decide with on the post-its. I sometimes even rearrange the notes until I get an interesting enough arc or sets of events. It is hard sometimes when you want to do a certain sequence and you don't know where it should go. Of course your story should make sense with the flow of things, but it is always a good idea to mix things up every once and a while.
