You can cut a postcard, or sheet of paper postcard size, in such a way that you can put yourself through it. Father and child fold the postcard in half, lengthwise. Start at the folded edge, near one end, cut through the double thickness almost to the straight edge. One eighth inch from the cut, start at the straight edge and cut almost to the folded edge. Start alternately at the folded edge and at the straight edge until you have made twenty-five or thirty cuts, all narrow strips. The last cut must start at the folded edge. Now cut each loop on the folded edge except the first and last loops. Open the postcard or paper. You will have a large circle. Put it over your head and let it drop to your feet.
