I chose to use the binding invented by Anne Goy. She apparently called it Criss Cross binding but it is universally known as Secret Belgian Binding. I chose it because the pages lay out flat when the book is opened. This is useful as there are many pages with instructions and this binding allows easy access to the information.
We followed many different instructions and after many wrong turns have a finished bound book. I learnt a lot in the process. Like most things, I should immediately produce another to consolidate my learning but I will probably flit onto something different.
