Cut the puff pastry into star shapes of varying sizes with star cookie cutters.
Arrange the starts on a parchment paper-lined baking sheet and prick them with a fork, so they don't get too puffy.
Brush each star with egg and sprinkle with flake salt and grated Thomasville Tomme.
Bake for 10 minutes or until golden brown.
Use a skewer to stack the stars into a tree shape starting with the largest star and ending with the smallest. Rotate one of the smallest starts vertically to top each tree.
