Page 1 - Creating the Backgrounds.

This tutorial is based on Dark backgrounds. First, create a 400x400 pixel document. Then get your fill bucket tool, and fill the background with the color : #161616. Then get out ur  Rounded Rectangle Tool.

It's below the Text tool, just click the Rectangle Tool for more options and then select Rounded Rectangle Tool. Alright, now draw a box. Look at the result image to get a small idea of what u have to draw.. make it large, because u will have to make another one inside too.
