CSS boxes & Tables

How do I do this?

[Lew3]

I would like to put eight rounded boxes on a page
with four on one side and four on the other.
Simular to four business cards laid out in a two by four pattern.
I already have the boxes made up, but need to know how to get the results I want.

Welcome to WebmasterWorld, Lew3!

Rounding edges are currently not supported by most browsers, so rounded edges are achieved by utilizing graphics along with normal css design.

If you need more info post the relevent code snippets (css and html).
