I slice a thin strip off the top of each mozzarella stick to create a flat edge, then press a sliced almond into it for a nail. I add two more almond slivers further down each stick to look like knuckles. Setting these aside on a plate keeps them from getting bent before you're ready to arrange them.
I unwrap the cream cheese block and place it directly in the center or corner of my board. Spooning the peach or fig jam over the top right before serving keeps it from soaking in too early. This becomes the sweet anchor point that balances out all the salty meats.
I set the wedge of gorgonzola near the cream cheese so the two anchor different zones of the board. Having two strong focal points makes it easier to build the rest of the layout around them. This also helps guests know where to start serving themselves.
I fold my salami slices into small roses by rolling one slice, then wrapping a few more around it, and nestle those in clusters. Prosciutto or capicola gets draped loosely nearby so it doesn't look too stiff. I like tucking these close to the cheeses so people naturally pair a bite of each.
I scatter the cubed cheddar or pepper jack into any open gaps, then lay the witch finger mozzarella sticks around the gorgonzola like they're reaching toward it. This is usually the step my kids get most excited to help with. It also adds height and visual interest to an otherwise flat board.
I tuck grapes, blackberries, and pomegranate arils into every remaining gap, letting some pieces spill slightly over the board's edge. Nuts and crackers go in small clusters or bowls so they don't get lost among the meats. This is also where I sprinkle in any Halloween candy for extra color.
I cover the finished board loosely with plastic wrap and refrigerate it for 15-20 minutes if I've prepped it ahead of the party. Right before guests arrive, I do a final scan for empty gaps and tuck in a few more berries or nuts. A quick garnish of fresh herbs at the very end makes the whole board look freshly made.
