It's great! ^-^ Really lovely job! And I imagine it would be a lot of fun to do (monotony in yarn is my bane...)! Definitely gonna be downloading your pattern!!
Oh I wish the pattern was mine but I just knit it. It just took me 2 balls of Paton's classic wool which is pretty inexpensive yarn. And if you did it in a smaller size than I did, you might be able to get 2 hats out of the amount of yarn.
