Place paper so that the long edges of paper will be parallel with the front edge of desk; bisect the back edge; four inches directly in front of this point, place a point; with this point as a center construct a four inch circle.
Beginning at lower side of circle, and having dividers open a distance of one and one-fourth inches, lay off six spaces in the circumference of the circle, working upward to the right; join all points in the circumference with the center; draw all chords to arcs, except the greater arc; construct a circular margin on left side of upper left triangle.

The base of the lower triangle shall be the upper side of a hexagon drawn within a circle; construct the hexagon.
Transfer to card-board to a scale of one to two; cut, crease, fold and glue, using circular margins on hexagon.
