Bookbinding

Thanks for the Feedback...humm..i tried a first attempt just to check if i understood how it is made, but obviously not , hehe. Looks simple, but i understand that it is not...i don t mind labour at all, that s how we learn the most, but would you mind to give a bit more details on how to do it?
If you have no time, don't worry, hehe, you did do a great job, if i must try again and again i will.
Thanks again!
