Step 1: Select a large, round platter or cutting board that will serve as the 'brim' of your witch hat.
Step 2: In the center of your platter, place the goat cheese log (or a small, cone-shaped bowl/stacked round cheeses) to form the 'peak' of the witch's hat. If using goat cheese, gently mold it into a conical shape.
Step 3: Arrange the dark cheddar, blue cheese, and other chosen cheeses around the base of the 'hat peak', fanning them outwards onto the platter.
Step 4: Artfully fold the sliced prosciutto or salami and place it among the cheeses, creating appealing textures and filling spaces.
Step 5: Scatter the blackberries, blueberries, grapes, clementine segments, and black olives over the board, focusing on filling gaps and adding pops of color, especially using darker fruits closer to the hat's peak.
Step 6: Arrange the charcoal crackers (or dark woven wheat crackers) and pretzel sticks along the outer edge of the platter to clearly define the 'brim' of the witch's hat. Place additional crackers in small piles within the board.
Step 7: Place small bowls of green hummus or black bean dip onto the board. These can go near the hat's peak or on the 'brim'.
Step 8: Tuck the gummy worms, candy corn, and chocolate-covered pretzel pieces into various nooks and crannies, adding a fun, spooky, and sweet element.
Step 9: Garnish the board with fresh rosemary sprigs to simulate branches or foliage. If desired, add small plastic spiders for extra Halloween flair. Serve immediately and enjoy your bewitching creation!
