Happy Halloween from Lizz @ Winged Crafts, here's the Hollowed Helm headgear from the World of Warcraft.
The model will be 20cm high and give or take the same in width. You can leave the bottom open and place a _FAKE_ candle in it to give it still that hollowed out pumpkin look. (remember...paper is flammable :P No real candles should go near it!)
