Some boring pix, but not for Linda, who asked if the pages lie flat with the open spine type of book. The answer is, yes, they do, pretty well, specially if your stitching is a bit saggy! Seriously, yes, compared to the codex type book with the signatures stitched to each other and stuck inside a board cover, they do indeed open and lie flat.
This one has an interesting, sort of shibori-folded and coloured, paper on the inside of the cover.
