Place paper so that the .short edges will be parallel with the front of desk; bisect the right and left sides; join opposite points; three inches from the left end of this line place a point. This shall be the center of a four inch circle; draw the circle; from the ends of diameters construct a hexagon within the circle; continue the outer edges of the upper and lower triangles indefinitely to the right; on the lower edge of the lower triangle construct an equilateral triangle, its apex pointing downward; from the apex of. this triangle draw a line parallel With the extended line above.

From the upper right corner of upper triangle set off on the upper line four two inch spaces; from the apex of lower triangle set oft' on lower line four two inch spaces; join all opposite points with lines that shall be parallel with upper right and upper left sides of hexagon.

The five upper triangles pointing upward, beginning at the left, shall be numbered 1, 2, 3, 4, and 5; the ten triangles in the middle, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15; the five triangles below pointing downward, 16, 17, 18, 19 and 20.

There should be circular margins on the left sides of the upper five and the lower five triangles and on the left side of No. 6. Transfer the drawing to cardboard to a scale of one to one.

Cut, fold, crease and glue.
