Choose a large size pumpkin for carving out this model.
Cut off the crown part and remove the inner flesh substance.
Carve a silhouette. Using stencils or any other drawing materials make the structure of ghost.
Carve out the outline space around the ghost and also carve out features like eyes and mouth.
Place a tea light inside the pumpkin and replace the crown.
Finally, you’ll end up with a circle of light around the dark shape, with lighted details.
