I’ve improved the method. On the plus side the books hold together better and are stronger and neater. On the negative, they still take a long time to make, even when I do several of the same size at the same time. For each book Somerset paper is torn by hand into 15 pieces, which are then folded and smoothed flat with a bone folder. They are carefully sewn together on to an inner spine of bookcloth. Boards are cut for the covers with bookcloth cut to fit between and hold them together, then two prints are cut to fit front and back. A liquid wax-like coating is then brushed on to the print to protect it.
