Travis showed me this trick the other day on how to make a quick grid in AI. I always make my own grids but this is a great way to crank out something good and fast when you don’t have the time to obsess.

First thing is to create your page margin that your information will be inside, then draw a big box. Select the box, go to Object>Path>Split into Grid… you will have your settings there to make how many columns etc you need… DONE.
