Thanks to HYZ's whole set of carving tools so that we are able to accomplish such a grand project. Basically you need to first stick a pattern on to the face of a pumpkin, pierce a whole bunch of holes into the pumpkin along the pattern line, saw through the holes to get a prototype of the pattern, polish the edges to make is smooth, light it up and Ta-Dah, you'll get one of these beauties!
I did the witch, the hard part is her hair and face, since they can easily get snapped off. But it turned out to be an art!
It wouldn't last very long, it gets all creased and shrunk and smelly after just a few days
