I was thinking specifically Of Knit Picks/Knitter's Pride/Knit Pro which has a lovely 90% Merino/10% nylon sock yarn, but there are lots of others. Katia I know, but I'd be interested in hearing more about your local brands. BFL certainly is a good sock yarn.

I always find it fascinating that yarns produced and spun right around here in US are often more expensive than stuff shipped around the world.
