Here's the link to a really good thread about closed book cakes, started by cserwa, who was looking for something like this herself. The first post is her summary of the responses she received.

SugarShack (Sharon Z) just came out with a new DVD on doing book cakes I used it for the Alice cake in my pics. It was a huge help to be able to watch it and see someone do it. I still need to practice but I was very happy with the results. You can get her DVDs at www.sugaredproductions.com
