lol heathfield, as soon as I saw the question, I thought, yes, they're all in my house, and breeding, I think there's a plot by these things to take over the world.
Yes, they've totally taken over my wardrobe too. Every time my husband brings home suits or jackets from the dry cleaners, they're all on wire coat hangers. The only good thing about them is that they take up less space than the plastic or wooden ones but my wardrobes are so tightly packed that separating all the wire hangers is sometimes like trying to untangle telephone wires! if you need some I'm sure your local dry cleaners will have thousands of the things and be prepared to part with a few.
