Thanks DB. I didnt notice the colour - I didnt have the light on and the main bathroom is badly lit. But it was HUGE. Nearly as big as my little finger.
Loving the idea (not) that it wants to hibernate - particularly since I have nearly every cupboard and wardrobe open in this house swapping the summer stuff for the winter stuff. Plus several piles of washing everywhere.
As for spiders I am sure there are loads in this house judging by the cobwebs. It would have to be one huge flaming spider though. Another cheery thought. The two things that I am inexplicably terrified of.
