I bought a kit with all of the stars years ago when my oldest was first born. You could easily, however, take a star cookie cutter, trace it, and while using a copier, blow it up a few sizes and then minimize it a few sizes. After cutting out the stars, you can use them as templates, or patterns for the stars.
After cutting and cooking your cookies, merely stack the stars from biggest to smallest, gluing them with royal icing. Decorate as you go with any kind of sprinkle. Let it dry overnight, and you will have a wonderful center piece for your holiday table.
