[support] Looking for tutorials on converting Photoshop PSD files into Drupal 6 themes

First of all, I'd like to mention how helpful this support list has been. I don't know how I could have gotten started with Drupal without it!

I'm just getting started with creating my own themes. I feel like I understand the structure of creating a Drupal 6 theme using CSS and template files, and I am also pretty familiar with Photoshop though I haven't worked much cutting up PSDs to use on a website. I was wondering if there were any good tutorials, resources, or books that show how to convert a PSD file into a Drupal 6 theme from beginning to end. Any help at all would be appreciated!
