This is a diffuser I used to use for burning essential oils. I originally intended to draw it for the EDM ceramic challenge so I finished it after drawing Paul's bell. I have trouble starting new things when there are others left unfinished. Mostly done with a B pencil with 3B in the darkest areas.
When I say I used to use it, it was to ward off evil spirits (the next door neighbour's) a few years ago but nothing relieves stress like the arrival of a removal van!
