just need a puff pastry sheet, which can be found in the freezer aisle of any supermarket.
you can use one sheet of puff pastry to make 4 servings of napoleon. i am only going to use half of one puff pastry sheet to make one large serving that's big enough for two (or two adults and a child) to share. it's important to remember that the puff pastry must be thawed so i take out what i need the night before, wrap it in plastic, and let it sit in the refrigerator overnight to thaw out. wrap the remaining puff pastry you're not using in plastic wrap and place it
