On one of the folded sheets, measure and mark 8 inches from the bottom left corner along the slanted edge and bottom edge of the paper. Draw an arc or curved line to connect the two points. Cut along the arc. Recycle the rest of the paper. Open the paper to the shape of a semi-circle or half-circle. You should see three crease lines meeting at a point in the center of the bottom edge. From the center point where three crease lines meet, draw a 4 inch line along each crease line. Cut along each line you just drew. Open up the paper into a circle shape. Draw a four inch line from the center along the two uncut crease lines. Cut along the lines you just drew.
