Zigzag Endpaper.
After the sheets are folded and pressed as described in the previous binding, the zigzag endpapers are prepared. In cutting these endpapers, four sheets of white paper to match the book are cut and folded, two of the folios being considerably wider than the book so as to allow for the fold e, Fig. 20. Each leaf of the large folios is folded back about one-fourth of an inch from the original fold. Then another folio, c, the same size as the book, is pasted under zigzag e, and the endpapers made in this way become the first and last sections. Folio b is the colored endpaper which is not inserted until book is sewed.
