It was gratifying to make, although I'm not sure I'll make another anytime soon. It's rather small not particularly sturdy -- not suitable for use as a carrying-around artist journal, for instance. It's more of a library book. If I remember correctly, these Egyptian books were stored face-up with the fore-edge pointing out, and they had metal feet on the back cover to protect the cover from being scraped as they were being removed from or replaced on the shelf. So formal content would be more in keeping with the structure of the book, and the idea of supplying (let's see: 12 signatures of 16 pages each equals) 192 pages of formal content is daunting!
But it is a very satisfying thing to hold in one's hand.
