Plan the cover paper to be large enough to allow for ½ inch lap to fold over the three free edges, but remember to allow a margin of vellum to show at the other edge. Plan the lining paper to be small enough to allow the foundation to extend beyond it at least ⅛ of an inch on all sides.
Make dimensioned sketches of all pieces and lay out and cut all parts. (See Plate XXXIX.) Place the newsboard foundations on the short piece of vellum the proper distance apart, with equal amounts of vellum extending under each. The newsboard, of course, will extend at each end a trifle beyond the vellum. When the proper position is determined, draw pencil lines lengthwise of the vellum indicating the edge of each cover. Put paste on the vellum and rub down well onto the newsboard forming the inside of the hinge. To make sure that the upper and lower edges of the covers are in a continuous straight line, place a rule or straight edge against one cover, extending across and beyond the vellum; place the second cover against the rule and the edges will be in a straight line. (See Plate XL.) Paste the second piece of vellum onto the outside and turn the projecting ends over the newsboard, pasting them down.

of the parts of a portfolio.
Properly place one foundation piece on the cover paper, allowing the vellum to show where it laps onto the newsboard, and draw around it. The amount of vellum which is to show is a problem in space division. Just how much will look well on the particular cover under consideration should be carefully thought out.
Apply paste to the cover paper, noting that it requires more skill to spread paste uniformly on a heavy paper than on vellum or lining paper. Place one piece of newsboard on the paper as previously marked, turn them over and rub down. A piece of cloth held in the hand and used for rubbing the surface prevents finger marks; or the rubbing may be done on a piece of paper laid over the surface. The cover paper should cling firmly to the foundation at every point and this should be assured before proceeding. Apply paste to the projecting laps, fold them over and rub down. Treat the other half in the same manner.
Plate XL. Pasting the newsboard
to the vellum back.
It is desirable to tie the portfolio together on one side at least. For this purpose secure tape of harmonizing color and ⅜ or ½ inch in width. About ½ an inch from and parallel to the front edges cut a slit through both paper and newsboard of the same length as the width of the tape. (This needs to be done with a knife or, better yet, with a chisel.) Insert a piece of tape from 6 to 9 inches long in each slit and securely paste at least 1 inch to the inside of the newsboard, allowing the greater length to project from the outside. Paste the lining paper on the inside of each half and this will cover the pasted end of the tape. The portfolio is then complete.
(B). By a different arrangement of tape the same kind of portfolio may be used as a magazine holder or cover for a paper book or pamphlet. Plan the newsboard foundations to project ⅛ of an inch beyond the book on three sides. The space between the two pieces of newsboard should be at least an inch greater than the thickness of the book so that the covers will lie flat when the book is inside. It will be seen that with so wide a space the inner edge of the newsboard will not extend as far back as the back of the book, and in planning the newsboard it should actually be narrower than the book. Make dimensioned sketches of all pieces and lay out and cut all parts.
