Well, here I am back in the USA. I had a completely wonderful and amazing trip, saw tons of wonderful things, spent some quality time with my boy and his family, and of course brought some yarn (or 'wool', as they say) home with me!
Would you believe that the department stores in the UK have better yarn than the craft stores in the US? John Lewis, which is a chain store, had such luxury yarn as Noro, Debbie Bliss, and this handpainted South American yarn, Mirasol Hacho.

I also got some Rowan Tapestry, in a shade picked out by my boy himself, for a pair of mitts. I bought four skeins, because by my reasoning, if I were making mitts for myself I would buy two skeins. And his hands are much larger, and he wanted longish mitts.

I ended up, however, with more than two skeins left over. I'm not sure what I'm going to do with them, but it's lovely yarn, so I'm sure I'll think of something.
