The foundation for each part is to be developed from a single piece of newsboard. The box and cover are to be covered with a thin paper. A great variety of paper for this purpose may be purchased, either figured or in plain colors.
For the box plan a strip of paper long enough to extend around the four sides and to provide for a lap where the ends join. Be generous with this lap, as it will be found that the paper “takes up” when it is pasted on. The width of the strip should be at least one inch more than the depth of the box. For the cover, plan covering paper like the newsboard development, but with its sides ½ inch or more wider to fold over the edges. Let the corner squares serve as laps. Make dimensioned sketches of all pieces and lay out and cut all parts. (See Plate XXIX.)
Along folding lines of the foundations score deeply with a knife, one blade of the scissors, or with a pin, and fold with the crease on the outside. It is essential to the success of the box to have this crease on the outside to insure a sharp, straight, and strong edge, which might otherwise be rounded, irregular, and weak.
Plate XXIX. Drawings of the pieces required in making boxes.
Fasten the corners of both box and cover together with pieces of tape or strips of vellum, lapping onto the sides. (See Plate XXX.) If possible, allow the corners to dry before proceeding further.
Paste the strip of paper around the box, allowing ½ inch to project beyond both top and bottom edges. Rub down well. Make a vertical cut at each corner of upper projection and fold and paste laps down on the inside. (See Plate XXXI.)
Make a V-cut at each corner of the lower projection, fold and paste the laps against the bottom. (See Plate XXXII.) It will probably be necessary to apply more paste before finally rubbing these laps down.
