The top pair are knit flat and seamed (you can see the seam in the top one), which I think means that the colourwork was knit flat, then seamed, then a heel and toe added on. Maybe? Anyway, they are lovely! Just a bit too big, but I had to have them (they were the only pair).
The second pair I didn't do a good job of photographing - the lacework is lovely, and more prominent. But I love the little cuffs! They had these in this yarn, and in a similar yarn with dog hair knitted into it! I think it was knitted in rather than spun in, from what I could see.
Anyway, I'm looking forward to a cosy winter wearing some of my favourite souvenirs!
