A birthday-present, commissioned by the mother of Tessa. She copied pen-drawings from one of Tessa’s sketchbooks. Pictures 2-5 show a ring binder, size a5, with metal corners. The next 5 pictures show a folder binder. The way the spine is constructed makes the binder thicker/thinner relating to the amount of paper it holds. Kater, one of my cats, was eager to ‘help’. But then he had to leave the workroom.
