I Would Love This Hat

I was watching Sarah Plain and Tall: Winter's End and saw this cute little bonnet with an attached scarf. It is so cute! It looks like it was crocheted or knitted. I would love to find a pattern for this. I am not sure that I could figure one out myself, but I might try. If anyone knows or has seen this pattern please let me know. I could just see my little Otter in one of these!
