Add the popcorn, gummy hearts, raspberry fruit snacks, and XO gummies to small bowls and arrange in the center of the board to anchor it.
Fan the Oreos around one bowl, then arrange the yogurt pretzels, pink M&Ms, Lindt truffles, white M&Ms, and gummy bears, strawberry rocks, and strawberries & cream licorice between the bowls, being careful to separate similar colors.
Then arrange the licorice pinwheels, Ghirardelli squares, candy skulls, chocolate heart cookies, sprinkle cookies, salted caramel chocolates, chocolate-covered pretzels, lip gummies, and sprinkle chocolate bars in a uniform pattern along the edge of the board or in a triangular pattern (points toward the center), being sure to separate similar colors.
Fill in any hole with smaller candies.
