I started this hat last year sometime, and only dug it out to finish yesterday. It is based on this pattern from Knitty, but I used two strands of wool and a larger needle. The light colored yarn was in the basket of good stuff Keith gave me for Xmas last year, and the grey is the stuff Emma brought me back from Ireland (12 years ago!).
I intended to felt the hat, but it was pretty cool looking, even though it is GIGANTIC. It will even fit my sister's giant melon.
