Unroll the pie crust and cut shapes out with cookie cutters. Unroll the can of crescent dough. Using half of it, cut shapes out with cookie cutters. Cut the remaining half into strips and wrap around the cocktail wieners. Place all of the cut outs and the cocktail wieners on a parchment paper lined baking sheet.
Bake until doughs are light golden brown, about 7-10 minutes.

In a small bowl, combine the cornstarch with both cheeses. Add the cheese to saucepan, in 3 parts, whisking continuously. Whisk until smooth and cheese is all melted.
Heat the queso cheese in a microwave safe bowl or small saucepan.
Place the cauldrons on the Halloween tray and fill with the cheese sauces. Arranged the dippers around the cheese cauldrons. Add the Halloween toothpicks to some of the bread, cocktail wieners, and potato rounds.
