Choose cutters with simple shapes; they're easier to handle and less likely to break. If you want to make small puzzles, cut dough into 4-inch squares, and use a single cookie cutter to punch out the center of each square while still hot from the oven. Working quickly, cut lines from edges of square to form puzzle pieces. Store icing in an airtight container at room temperature up to 1 week.
