Coptic Bound Sketchbook

In this book, four holes were drilled and then sewed into a braid like pattern through the signatures. Signatures are several folded pages folded in half to create the book; multiple signatures make up the book.  It's a fun way to bind a book and it looks pretty.  It's tough though to keep it tight as your weaving in the thread.  String should be waxed to make it easier.
