Place paper so that the long edges shall be parallel with the front of the desk; bisect the back edge; four inches in front of point place a point J with this as a center, draw a four inch circle and a one and one-fourth inch circle, the one and one-fourth inch circle to be indicated by a dotted line; place points in circumferences indicating ends of horizontal diameters; from these points divide the circumferences into six equal parts.

In both circles connect the upper right points with upper left; the upper right and right: the right and lower right; and the lower right and lower left.

Join the upper left corners; the upper right; right; lower right; and lower left. On the upper side of lower frustrum erect a five-eighths square; on the upper, right, and left sides of this square construct circular margins.

Construct a circular margin on left side of upper frustrum.

The base of upper frustrum shall be the upper edge of a square; construct the square.

Transfer to a scale of one to two, and cut, crease, fold and glue.
