Plate XXVIII. Relative positions of newsboard and vellum in making the cover of a clipping file.
Draw a line through the center of the vellum showing where the back edge of the small piece of newsboard should come. Lay main part one-eighth of an inch from this line and draw around the edges of both pieces except where the large piece projects beyond the vellum (see Plate XXVIII). Apply paste to vellum, lay pieces of newsboard in place, turn it over and rub down. Cut from the projecting vellum a small piece even with the ends of the hinges as far as the outside corners. Apply paste first to projecting ends, then to long strip; fold over and rub down.
Properly place cover on cover paper and draw around it. Apply paste to cover paper and finish as when vellum is used for entire cover. Paste in the lining paper and dry under weight.
Strips of vellum about 2½ inches wide and one inch longer than the envelopes should be folded lengthwise down the middle to form guards. Cut strips of newsboard three-quarters of an inch wide, and of the same length as the envelope. Apply paste to half the vellum and lay the newsboard on it with one edge against the center fold. Against the other edge of the newsboard lay the lower edge of the envelope with its ends and the ends of the newsboard in the same straight lines. Treat the ends of vellum in the same manner as on the covers. Punch holes in covers and guards, insert eyelets, and fasten together by tying, or with paper fasteners.
Problem IX
BOXES
Time: 6 hours.
Materials: Newsboard, stay-tape or vellum, and a thin paper.
First determine the size of the box, which should be made for a definite purpose. Consider the proportions of the width, length, and height; also the height of the sides of the cover.
A box consists of foundations of newsboard, the edges of which are stayed with strips of tape or vellum, and the outside covered with paper. The cover should be larger than the bottom by ⅛ inch in both directions to allow it to slip over the box. This amount will vary somewhat with the thickness of the newsboard, the paper with which it is covered, and the skill of the worker.
