In Silvie Turner’s The Book of Fine Paper (1998), as well as the many descriptions and photographs of hand-made and other fancy art papers, there is a folder within containing eighteen small samples (each about 2¼"x1¾") arrayed “so that their character, weight and texture can be felt”. These range from some filmy 10gsm “Khadi Himalayan” stuff from Nepal to a thick & heavily-textured French 350gsm “Colombe/Larroque Duchêne” paper.
Other manufacturers featured include Fabriano, Hahnemühle and Dieu Donné. The book as a whole has more emphasis on papers for artists and craftspeople than the writing papers that more specifically interest me, but it’s nevertheless a highly informative volume and one I’m glad to have on my shelves. Mine is an ex-library copy that once belonged to the University of Salford, where it seems not to have been much used.
