To make the coptic journal, I cut the sides off the box, with the label on the front of the journal and the nutrition information on the back. (Maybe that's really just a way to keep me on my diet.) I like the shape of this book, very tall and narrow--it's over 10" tall but only 3" wide. It has seven signatures of alternating peach and beige paper (for the peanuts and nougat, of course).
One problem with this book is the answer to the question of why I don't often use corrugated cardboard for books (besides the non-archival quality). Just as I was finishing the stitching, the cover bent in a couple of places. Once you get that sort of bend/crease in cardboard, it's there to stay. They will never go away, but this book will benefit somewhat from being under weights for a day or so.
