Place paper so that the short edges will be parallel with the front of desk; bisect the back edge; six inches from this point, directly towards the front, place a point; this shall be the center of a one and one-half inch horizontal line; draw the line, marking the left end A, and the right end B; on line A B construct a pentagon as in pentagonal prism.

The upper right corner is C, the upper left, D, and the upper, E. Join with ruler C and D. and draw a line one and one-half inches long to the left from D; join with the ruler C and A and draw a line one and one-half inches long- diagonally downward to the left from A. With the outer ends of these lines as centers, and a one and one-half inch radius, draw an intersection of arcs to the left; join points making a pentagon; on all remaining sides of first pentagon construct a similar pentagon.

On the lower left side of lower pentagon construct a pentagon; on the lower side of this pentagon construct a pentagon; on remaining sides of last pentagon construct pentagons.

On the series of six pentagons above there shall be circular margins on the left side of upper right; on the lower left side of upper left; on the lower right side of lower left; on the upper right side of lower; on the upper side of right.

On the series of six below, there shall be circular margins on the upper left and lower left sides of the upper pentagon; on the upper left, left, and lower left sides of left; on the left, lower, and right sides of the lower left; on the lower, lower right, and upper right sides of the lower right pentagon; and on the lower right, upper right, and upper left of the right pentagon.

Transfer drawing to a scale of one inch to one inch; cut, crease, fold and glue.
