Rather than carving a pumpkin with a lid on it, this one is carved with a flame patterned top ridge.
You can extend the top of this pattern all the way around the pumkin.
Finished it off with a pie plate full of lighter fluid or lamp oil and let her rip. This one is designed to burn.
The gray areas represent where you cut away the orange skin but leave some flesh. The black is cut away completely.
