ALL of them hand-knitted, by me, unless that's just an edge of a commercial (thermal) one poking up at top right. And there are more below those; I haven't counted accurately recently, but probably about 40 pairs? And they are indeed very cosy!

(I'm currently wearing the pair you can see at the front centre, which are knitted in Knit Picks Felici 'Time Traveler', and the pattern is Earl Grey. Thought you ought to know.)
