Covering Leonardo; Art of the Book 08

Apologies for the long delay in posting, life intervened.
Having sewn the text block, the next step is to prepare the cover for "Leonardo Dreams"....
          In this binding the cover is made off the book, and laced on afterwards with the vellum slips. 
The first step is to make a template to use as a pattern to cut the leather. When the book is part of an edition I lay it out on the whole skin to make sure that I can cut enough covers to complete the whole edition. It is a mistake to assume that you will always be able to buy the same shade again as dyestuffs are sometimes discontinued or unavailable, as I have discovered in the past! 

          The template is marked up to show the turn-ins and the spine area. I usually cut one cover to make up a proof, and then when I'm satisfied that the binding works, I cut the covers for the whole edition. On this template you can see the projection on one side for the tab that will fold over the fore edge. This tab references the style of a portfolio and with the ribbon ties, protects the fore edge of the book. It will be lined with a thin piece of leather.

          On the cover itself I have marked out the turn-ins, the tab and the spine area. The shaded area will be cut off before I start to pare the leather. Leather for bookbinding, even on small books needs to be sufficiently substantial not to tear, so I don't use skiver leather. When the leather in the spine area is pared correctly it will fold over neatly at head and tail. The tab will be blind tooled with a double-line fillet wheel before the boards are adhered to the leather. 
          A note about book boards: binders board is hard-rolled and dense, and in the UK is called mill board and in the USA called Davey board. The boards need to be thick enough that they don't bend or warp when the leather is applied. I usually use not less than 1.6 mm thickness. Of course, for larger books heavier boards are necessary. After cutting the boards, on small books I often bevel the edges so that they look less heavy, but that is purely for appearance.

The Art of the Book 08 - CBBAG's 25th Anniversary Exhibition
          If you are anywhere near the University of Victoria on Vancouver Island between now and January 5th, be sure to check out this exhibition. It is in the McPherson Library, in the Maltwood Gallery, and is a juried international exhibition of books and the book arts. The exhibition is a five-yearly event staged by the Canadian Bookbinders and Book Artists Guild, (known as CBBAG, pronounced 'cabbage') and includes fine bindings, fine printing, paper making, calligraphy, artists books, and  paper decoration. Entrance free - I highly recommend that you see it.

The exhibition opened in Toronto in October of 2008, and has travelled to many different venues across Canada, finishing at UVic. It is an extraordinary achievement, largely due to the hard work of two dedicated people, Shelagh Smith and Susan Corrigan, who have been organizing this for twenty-five years.
