The pumpkin's stem kind of looks like a witch's hat!
I used various-shaped leaves as a template for the design I carved out.
As for the pumpkin seeds, I dried them out in a warm oven, then tossed them in melted butter, salt and pepper, and roasted them at 300 degrees for about thirty minutes. The hulls were crisp enough to break open with my teeth, and the kernels inside were still tender. Yum yum.
