Like a beacon, this table number declares its location in all directions. To make it, use a computer to print numbers onto pieces of colored cover stock (or have numbers calligraphed). Trim the papers to 6 by 7 1/2 inches. For the feet, cut 1/2-inch squares from both corners on bottom edge. Measure over 1 inch for each foot, and mark. Cut out a 3-by-1/2-inch strip between marks. Crease each sheet down the middle, and join the 3 pieces with rubber cement.
