Your check list should start and evolve at the very beginning of your event; brainstorming list, time line list, food/grocery list, drink list, guest list...you get the idea. But remember, no matter how diligent you are with all your lists; there is something that will happen that you did not for see, just remember that this is ok and keep going.
I personally, like to add in a line in my budget for "unforeseen costs"; just because you don't know what it is going to be, doesn't mean you can't try to prepare for it. I also, like to put in my time line lists a section for breathing, and celebrating a job well done. As silly as that may sound, you would be amazed how often you will over look yourself.
Now that you're checked your lists twice...or more, enjoy!
