A free pattern for a Santa hat... (with US needle size conversion fixed). Neither of the yarns are available anymore, but you at this time of year you can easily find nice quick-knit yarns in the bulky section. Lion Brand Wool Ease "Thick & Quick" would fit the bill very nicely and inexpensively.
The fur yarn used for the pattern was a good stable bulky yarn with extra fuzziness that made a good fabric on its own. If you can't find something similar, use a nice chunky weight smooth white wool held together with a fuzzy/furry/eyelashy sort of thing. Lion Brand's Festive Fur would work brilliantly.
