Fold down the top layer by applying the valley-fold along the red dash-line of the step #27.
If the day is done, if birds sing no more, if the wind has flagged tired, then draw the veil of darkness thick upon me, even as thou hast wrapt the earth with the coverlet of sleep and tenderly closed the petals of the drooping lotus at dusk.
