Three rectangular pieces of tar or cloth board are cut, two larger ones for the body of the portfolio and one smaller one for the lid or flap. The large pieces are lined with paper on the sides which are to go inside. This prevents warping when the outside covering is put on. A strip of book cloth or buckram is cut about two inches wide and long enough to reach around one side and the two ends of the body of the portfolio. This strip is folded lengthwise in the middle with the wrong side out. Then each half is folded lengthwise in the middle, turning the wrong side in.
Thus folded, the strip is pasted around the ends and bottom edges of the two large boards, mitering all the corners. Fig. 50. Then the flap is attached by means of two strips of cloth, one above and one below, and the edges are bound to correspond with the body. Then cover paper is pasted on all the uncovered surfaces of the boards, lapping one-eighth of an inch over the edges of the cloth wherever the paper and cloth come together. Scores of modifications may be made of this style of portfolio.

EIGHTH GRADE.
1. Book for Mounting Drawings and Pictures.
Heavy cover paper is used for this book and is cut into large folios. Then strips of the same paper about one and one-half inches wide and as long as the book is high, are folded lengthwise in the middle. One of these folded strips is fitted over the back and one inside of each folio, Fig. 51, except the first and last. This provides for the pasting of a mount on each page of the book without making the body of the book thicker than the back. Sewed on tapes. Cover treated exactly as that of the Library Binding, page [27].
