Frosttwig, Iceneedle, and Snowtriffid (well, lurking at the corner of the building like that, looks to ME as if he's hoping to ambush dinner ...)

Firebird socks

And more from the same designer:
Labyrinth
Tree of Life
Selkie
Mirror Mirror
Naiad (socks that are knitted sideways rather than the usual top-down or toe-up)
Snow Queen

All from a book full of fairy tale- and folklore-inspired sock patterns called The Enchanted Sole
