Shape the pumpkin out of red cheddar slices using a heart-shaped cookie cutter first, then trim with a glass to get the rounded base (I used a Pac-Man cookie cutter).
Peel some cucumber for the stem.
If you want to add dimension to the pumpkin, as I have done, then you can shape a piece of cheddar for the middle section and two pieces to the side.
Place the pumpkin on top of the crostini and add candy eyes.
Mummy Crostini
Slice the baguette and top with cream cheese.
Cut a piece of cucumber about as wide as the bread you are using.
Peel the cucumber and then cut long rectangular pieces.
Slice these pieces into strips.
Place two candy eyes on top of the crostini and then top with the cucumber strips.
Spiderweb Crostini
Slice the baguette and top with cream cheese.
Squeeze the balsamic glaze into a piping utensil or bag.
Pipe three circles onto the bread, one bigger than the next.
Drag a toothpick from the center to the edge of the bread to create the web details. I did this eight times.
Arrange all the crostini on a platter and top with plastic spiders.
