Sadie has designed socks inspired by Tzenni, and blogged about it here! They have roses and staircases on, and they are awesome.
Also, I just said to my D&D players ‘My books inspired someone to knit socks!’ and they looked back at me with expressions of ‘Your books make people’s feet cold?’
(Actually, if my books do give anyone cold feet about the merits of taking up with someone who bears a resemblance to, say, Kjarten or Sorszenna I shall be overjoyed. But the socks are enough of a source of joy in themselves)
