Ladies and Gentlemen, I give you: the Weeping Angel Toilet Roll Cosy.
The ploy is to literally scare the shit out of the toilet-goer. My bathroom light takes a few minutes to brighten up so any nighttime trips to the toilet are conducted in a semi-twilight lighting with long shadows. With this li'l lady guarding my cistern, I may have to invest in a bedpan.
BTW, I was too excited to finally finish this to get a good picture, so I may have to repost with better pics!
