That is a GREAT article, Diana, thanks for linking to it!
It seems to me that a lot of the sweaters currently in mass-market stores being marketed as Fair Isle are actually Icelandic Lopapeysa-inspired. Right?
I would love to know more about the history of these different forms of colorwork. Given the historical interchanges between Norway, Iceland, and the Northern Isles of Scotland I imagine there must have been handicraft influences passing back and forth as well...
