Felting again

The teacosy is finished, ends sewn in, felted. I fished it out of the washing machine after the wash had finished and it hadn't felted! Then I remembered changes of temperature also help felt wool, so I switched the rinse to 'cold' and when the machine had finished it had felted, hadn't shrunk as much as I had hoped, but definitely felted. I'll take some photos today for you to see.
