I posted the tutorial of how I make my texture plates today. You can read it at http://www.polymerclaybeads.blogspot.com/.
I also posted how I measured the amount of clay to use with the Bead Roller.
Just for your information, I am so addicted to the CD film technique that I cannot stop making them. So, Scott, my dear, you are the one to blame. I put more picture on my web album, if you want to see more. :)
