felted handknit mobile phone cosy

I have a new phone and made this bag/sock/cosy to protect it out of some lovely yarn that my mum send me some months ago. Annoyingly, it's shrunk more length than width-wise, and has actually shrunk more since th pic was taken so the phone peeks out, but its actually ok, because it means i can see when i have a text message without taking it out of its bag.
