We had rubber stamps custom-made for table coverings and bunting; download the template here. The stamps were a few inches wide and spaced a couple of inches apart. We used washable fabric paint (from crafts stores) and imprinted the stars onto lightweight fabric.
Lay material on a flat surface. For table coverings, it should be just narrower than the table's width and long enough to allow several inches of overhang on ends (for bunting how-to, click here). With a foam brush, dab a small amount of paint evenly onto stars. Stamp, spacing evenly and reapplying paint after each imprint; dry. We stamped table coverings 5 inches in from each long edge; we stamped bunting lengthwise down the center.
