Here's where we make the witch hat. This step is optional. You can put any hat on your pumpkin.
This is where the poster board comes in. It can be any color. I have chosen to paint it black.
I used fan covers to make the big circles.
The first circle is going to be 18 inches (45.72cm)
Lay the fan cover or another big circle in the middle of the poster board and trace it.
Carefully cut it out with scissors.
Next cut about halfway down from the bottom, then cut halfway from the side
The circle should have a quarter removed.
Take one side of the gap and fold or roll to the other side making a cone. You can adjust it to the size of your pumpkin.
After adjustments, you can glue or tape the cone together.
