Pumpkin

 Cut a lid from the top with a 45 degree slant to the cut, big enough to get your fist through and scoop out the seeds and fibre.

 Use a sharp and thin bladed knife to cut out the shapes in the pumpkin.  Scoop out any excess flesh and put aside to make a pumpkin pie (you will need about a pound of pumpkin flesh).

 Mark the position of the lid to ensure that it fits well.

Butterfly eyes and fangs are the theme of the day.  If it's dry on Halloween, this one will go on the garage roof, otherwise it may end up in the window.
