This should be planned and worked out in the same manner as the Sketch
Book, but it should be somewhat larger, possibly 6 × 8½ inches. For the
leaves, screenings or wrapping paper may be used.
To prevent covers from flaring after the book has been filled, the
thickness at the back should be increased by additional folds in the
paper, as shown in Plate XXVIIA. The “stub” should be about one inch
wide after it is folded. The Japanese method, which is to fold a very
long strip many times in the same manner, forms a pleasing arrangement
(see Plate XXVIIB).
