This is really worth watching. I recommend finding an hour to set aside, knit, and watch this:
I love the sensation The Prince of Wales (one of the Edwards) caused in the 1920s with a knitted vest that was 'almost vulgar' in it's brightness, and 'shocking' in it's informality! I love that he was such a sweater icon, and basically put Fair Isle on the fashion map. And did you know that in the 1930s the most fashionable swimsuits were knitted?!
