This is actually a post for a swap (which is now closed). I didn't join the swap but used this post to learn how to make the bag books.
As I am typing this, I know that the gallery is down, so if the links to the pictures don't come up, be patient until the the gallery is up and running. This is a fantastic tutorial!
If this isn't exactly what you were looking for, I suggest you click on the search engine and type in paper bag book, or some such thing and see what you come up with.
Good luck,
Kathy
