Calcifer is cute.
I made him out of plastic water bottles and cellophane.
Once I had cut out the bottle to the desired shape, I took a cigarette lighter and curled(melted) the spikes to look more flame-like. I coloured it with copic markers.
He also has a miniature light inside that shines in the dark.
