I read about natural fibres and decided I'd tell you about wool. Here are some amazing facts...in the form of a story.
But my story doesn't start with a sheep but a sheep dog.
My border collie, Zeb has longish hair for an outer coat and short, thick fur for an inner coat. So he keeps dry, too.
When spring comes and the days start to get warmer Zeb sheds some of his fur so he will be able to keep cool during the hot days of summer (if we get any hot days this year, that is).
