Hello Sly Cat from Perth. I've an igloo built using bucket shaped snow bricks (made using a plastic bucket - isn't the web great for finding stuff out).
You know, I may just ask to borrow some spares if the weather gets as cold as it did last week! We're not used to all this snow stuff...up until a few years ago, there were parts of the country that could hardly remember what snow looked like!
At the moment, my little corner of the south west has thawed out - but I'm sure it won't last.
