This is something I wanted to do back when I did the snowmen - believe it or not, I tried. For some reason my MilkShapeFu wouldn't let me shape the hat the way I wanted, lol. This year I decided to try again..
I'm not 100% happy with the texture but I thought he's cute enough to share. The red is the mesh and there are the 4 recolors. He can be found in Deco>Misc for 5 simoleons. CC in pics is by Simply Styling, Cassandre, Billy Jean and Oh Behave.
