The "Top Sheet" and "Bottom Sheet" should be printed on the two sides of a single piece of paper. Flip the paper
over (left to right) after printing the yellow side and send it through the printer again to receive the
white-side markings. Hold it up to the light to see if the small central X on each side is aligned correctly. To
have the details come out in the right place, the near surface of the Bird Base in Step One should show the three
and a half portholes.
