TO make, by folding and cutting, a square, a circle, a regular octagon, a four-pointed star, an eight-pointed star, a quatrefoil, an octafoil, a four-leaved rosette, an eight-leaved rosette, from a square, circle, or any regular or irregular plane figure.

The Square

Fig. l

For Figs. 2, 3, and 4, fold 1 on 2, and crease with the thumb-nail. For Fig. 5, bisect the angle at o in Fig. 4, and fold.

The Circle

Fold to Fig. 4, and cut from 1 to 2. Points 1 and 2 are equally distant from o.

The Square

Fold to Fig. 4, and cut from 1 to 2. Point 2 is a bisection of 3-0.

The Regular Octagon

Fold to Fig. 4, and cut from 1 to 2. Points 1 and 2 are equally distant from O.

The Four-Pointed Star

Fold to Fig. 4, and cut from 1 to 2. Point 1 is a bisection of 3-0-.

The Eight-Pointed Star

Fold to Fig. 5, and cut from 1 to 2. Point 2 is nearer to 3 than to o.

The Quatrefoil

Fold to Fig. 4, and draw on the fold a semicircle, and cut from 1 to 2. Point 1 is the tangential union of the semicircle and the line 3-4.

The Octafoil

Fold to Fig. 5, and draw on the fold a semicircle, and cut from 1 to 2. Point 2 is the tangential union of the semicircle and the line 3-0.

Four-Leaved Rosettes

Fold to Fig. 4, and cut from 1 to 2.

The Circle

Fold I on 2, and crease with the thumb-nail.

FIg,5

For the square, fold to Fig. 3, and cut from 1 to 2. For the octagon, fold to Fig. 4, and cut from 1 to 2. For the four-pointed star, fold to Fig. 4, and cut from 1 to 3. Point 3 is obtained by trisecting 2-0.

Quatrefoils

Fold to Fig. 4, and cut from 1 to 2.

Eight-Leaved Rosettes

Fold to Fig. 5, and cut from 1 to 2.
