I have a hardcover from Everyman's Library whose fore-edge is a concave crescent. (See first picture.) Is there a word for this effect? Second, and more importantly, how might I achieve this effect in manual bookbinding?
Edit: I have added three pictures of a book I am currently working on, which is bound using a French link stitch (and kettle stitch). Is it at too late a stage to attain the desired effect?
Chris H's comment helped me realize that the French link stitch is loose enough to push the pages back to form something like the desired effect. It then becomes a question of, first, doing something at the spine to secure this shape; and second, rounding out the sort of plateaux formed at the fore-edge by so pushing an already square-cut fore-edge into a crescent shape (see fourth picture). As regards the first question, is there a way to do this without covering the parts of the spine where stitching is apparent?
