Use ordinary grocery-store matchboxes to count down the days till Christmas. Just hot-glue the tops of empty boxes to one another to form rows (start with nine boxes for the base, and decrease by two until you have a single box). Cut wrapping paper to cover each section; secure with hot glue. Next, hot-glue the rows in a pyramid shape as shown. Use number stamps (available at craft stores) to mark the boxes 1 through 25, then fill with candy and trinkets.
