I created a dummy book, just using regular printer paper.
The elements in a finished Woven Codex are:
a cover and a signature block. The cover can be attached to the signature block, but you will cover up the binding. I have seen this structure done others without any cover at all, so there can be some variation in the final piece.
Close up of binding -
The signature block is made up of two signatures that are woven with a card in the center. You can see the tyvek strip (that is used for the weaving) on the front and back of the middle cards. It is not visible on the signatures.
And the signatures packets are divided by a small gap.
The tyvek strips are attached to the first and last signatures.
As I said above, going forward, I will put information about the structure on Week 1. I find its very helpful to know this as you are planning your content for the book out.
Happy Book Making!
