As the negatives must be sized, it is necessary to use films. A camera using films 3-1/2 by 3-1/2 in. will make negatives that can be trimmed 1/4 in. on each side to make prints 3 by 3-1/4 in. Each two negatives making a pair are fastened together, properly transposed, by folding a narrow strip of black paper like a long, V-shaped trough, pasting it, and putting one on the bottom of the two negatives, as they lie side by side, and one at the top; saddle fashion. This can be done still easier by using strips of passe-partout binding, or strips used for binding lantern slides. If so desired, the use of black paper can be carried farther by cutting the top strip of binding paper in such a way that it gives the round corners to the top of the prints. A narrow strip through the center and a binding of black paper along the two end edges make a mask unnecessary in printing.
How to Make a Paper Drinking Cup
Every person should understand the simple method of making a paper drinking cup. It may be necessary at times to make quick use of medicine and with no cup or spoon convenient, the pyramid-shaped cup shown in the sketch is a useful emergency utensil.
Folds in the Paper (Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5)
The paper cup is made as follows: Cut the paper into a square and crease it on the dotted lines, A G, F B, and C D E, as shown in Fig. 1. Fold the paper in half through the line C D E to form a rectangle, Fig. 2. Fold points C and E inward until they meet inside the triangle to form the shape shown in Fig. 3. This makes four distinct corners, F, G, A and B. Fold the paper over on the dotted line and bring the points A and B together as in Fig. 4. The extreme edges meet in the central line indicated. Reverse the paper and fold the points G and F in like manner. Turn the points A B and F G inward and fold on the dotted line, and you will have a perfect pyramid-shaped cup as shown in Fig. 5.—Contributed by Miss Margaret S. Humphreville, Mt. Pleasant, O.
A Hand Corn Sheller
A very handy device for shelling corn, and especially popcorn, can be made of a 1-in. board on which is fastened a piece of metal lath. The edges of the metal lath are bound with a strip of wood nailed to the board.—Contributed by Ulysses Flacy, Long Beach, California.
