Here is a fascinating paper-cutting trick where you can make three popular cross shapes. If the paper is folded according to directions, a single cut of the shears will produce a Latin cross, which has one long arm and one short arm, a Greek cross, in which all arms are equal in length, or a Maltese cross, with arms thin at the center and wide at the ends.
Take a long sheet of paper like that in Figure 1 and divide it on the line AB so that you have a square and a small oblong.
Fold the upper left corner down on the dotted line, which will produce figure 2.
Then fold the upper corner down to the left on the dotted line in figure 2, which will produce a paper shaped like figure 3.
Now fold the left side over to the right on the dotted line in figure 3, which leaves you with figure 4.
To produce the Latin cross, cut along the dotted line in figure 4.
For the Greek or Maltese cross, cut along the line CB in figure 4 and discard the lower part of the paper.
This will leave the triangle DCB as in figure 5.
A cut along the left-hand dotted line will produce a Greek cross, while a cut along the right-hand dotted line will produce an equally perfect cross of the Maltese pattern.
