To dry leaves, lay down a sheet of newsprint, followed by paper towels. Arrange leaves on paper towels, then place a second layer of paper towels and a sheet of newsprint on top. Set stack in a phone book, and place in a dry, ventilated spot for several days. To make place cards, use a gel-ink pen -- ours had white ink, but metallic shades will also work well -- to add guests' names.
