Child's Leprechaun Hat - Part 1

So recently my mother brought me a bag of yarn she had left over around that she wouldn't use again. I saw the Emerald green of this yarn and my mind started searching for something to make. This is what I came up with

I did do up a pattern but would like to make sure there is no errors and maybe some more sizes. What does everyone think?

 Little Lady trying it on for the first time. She loves it.
She is such a doll. If I do say so myself ;)

Pattern will follow after writing and testing is done. TY
