Be careful not to get the egg wash on the sides of the pastry cutouts, or you won't get as much puff in the pastry.
Make this puff pastry wreath up to 2 days before the party, and wrap tightly with plastic wrap.
Use bell- or star-shaped cookie cutter to cut pastry into 24 pieces, but do not make wreath; bake pastry cutouts as directed. Microwave Brie on Medium (50%) 2 to 3 minutes or just until soft and warm. Arrange puff pastry cutouts around cheese. Garnish with fresh thyme, raspberries and crab apples.
Place cheese and puff pastry wreath on slab of marble.
