I finally posted an example of how to use pattern fills in photoshop to "fake" a rendering. Be sure to check out the tutorials section. It is funny that the more website and graphics work you do, the worse your own personal site is. I need to rework the site for some CSS and new scripts that I have been working on. All in good time. :)
As for the tutorial, Photoshop is a tool that I use for a lot of post-processing work and if you plan to do any type of graphics work you should learn to use this tool effectively. The pattern fills are a simple tool and can be used in more ways that I share with you here.
Happy Rendering...
