Cocoon pattern?

[Nabber13]

Hi there. I am not a knitter at all so I am actually looking for a pattern or directions that I can pass along to my sister-in-law who is a knitter.
I am looking to have something like the picture made. It looks pretty basic too me but again I'm not a knitter (I'm a photographer).
Can anyone help??

That is so cute!! No I have not seen a pattern for anything like that. I hope someone has because I would love to make one.
