These cheerfully colored umbrellas sporting seating assignments dot miniature sand dunes at the entrance to a summer reception.

You'll need a 1-inch-deep tray, a sheet of 1/4-inch foam board cut to fit into bottom of the tray, and some sand. Lay the foam board in the tray, and cover with sand. Drizzle sand unevenly, sifting a bit more here and there to form dunes.
Print your seating assignments onto colored paper, and cut them into strips; glue strips to the shafts of the umbrellas.
Poke the umbrellas through the sand into the foam board at an angle so guests can easily find their names.
