A. A Sketch Book
Plate XXV. Freehand dimensioned sketches showing parts
of a sketch book cover.
In making dimensioned sketches for the various parts (see Plate XXV) determine first the size of the pages and plan the covers to extend beyond them about one-eighth of an inch. Make the sketches of the pages and the newsboard foundations. Lay out and cut the latter, of full size, and then from either a long or short side of each, in accordance with plan, cut a strip to form a hinge. The width of these strips may be from three-quarters of an inch to one inch. Vellum should be planned to cover completely one side of both pieces of each cover, to fold around the small piece and to lap over onto the large piece about one-half inch. It should also fold over the other three edges about one-half inch. (See Plate XXVI.) The lining paper should cover to within about one-eighth of an inch of the edges of the large pieces and should not extend onto the hinge. Constant bending soon breaks paper, but with ordinary use does not affect the tough vellum. Make dimensioned sketches of these pieces (see Plate XXV) and lay out and cut all remaining parts.
Plate XXVI. A diagram showing the position of the two pieces of newsboard on a piece of vellum.
Properly place main part of newsboard on vellum, drawing around it. Lay small part one-eighth of an inch from main part and draw around it. Remove the pieces of newsboard and apply paste to vellum inside the pencil line, being careful to cover the surface smoothly and evenly; lay both back pieces in place, turn the vellum over and rub down. Cut from the projecting vellum on the hinged side a small piece even with the edges of the hinges as far as the outside corners (see Plate XXVI), and clip off the outside corners as before described. Apply paste to projecting vellum, fold over first the hinged side and its opposite, then the other two sides, and rub down. Paste the lining paper in and dry the covers separately under weight. Remember to place newspaper or blotting paper between each pair, otherwise the moisture from one will cause wrinkles in the other.
For the leaves, use drawing paper, which may be cut singly or in folio (with single fold). The latter method is preferable, as folded sheets are easier to place at the back, look better, and are more secure.
