Create a grid pattern

Hello, I am working on this flash header for a website…

http://www.videolinktechnologies.com/movie.swf

I need some kind of decoration in the background instead of just having solid blue…

Anyone know how to make a “grid pattern” in the background?

I turned on the grid and traced the lines… but the lines keep snapping to each other and it takes forever… especially if you use small squares…

Any ideas? Or anyone know how to make a grid of squares easily?

thanks
