Place paper so that the long edges shall be parallel with the front of desk; bisect the left edge; bisect the right edge; connect points of bisection; on this line four inches from the left end place a point; four inches to the right of it place another; with these points as centers, draw two four inch circles; from ends of diameters divide the circumferences into six equal parts.
In circle to left, connect upper left point with lower right; the left, with lower left; lower left with lower right; upper left with upper right; and upper right with right.
In circle to the right, connect the upper right and lower left points; the lower left and lower right; lower right, and right; lower left and left; left and upper left; and upper left and center.
On the upper side of upper triangle in the circle to the right construct an equiangular triangle with apex pointing upward; on the left side of this triangle construct a circular margin; connect the lower right point in circle to left with lower left in circle to right.
On the left side of upper rhombus in the circle to left construct a circular margin.
The left rhombus in left circle is side No. 1; the upper rhombus, No. 2; the one to right of No. 1 is No. 3; the rhombus including upper left and lower left triangles in the circle to the right is No. 4; the lower right rhombus in same circle, No. 5; and the rhombus including the upper triangle and one constructed upon it, No. 6.

There should be circular margins on left side of No. 1; on left of No. 2; on upper left of No. 4; on upper, lower, and right sides of No. 5; and upper left side of No. 6.
