I ran across this brilliant site the other day while cruising the 'net. I suppose nobody remembers now, but my first question when I joined MWK was about ganseys, and they still fascinate me. Haven't actually started one yet, partly because it's been 90 degrees every day here and the last thing I want on my lap is a pile of wool right now, but also because I'm still doing some research first.
Well anyway, I found this site called "A Fisherman Knits" by Aaron Lewis, who seems to be a combination knitting god and historical researcher. He was also fascinated by ganseys, especially the way they would have made them a few hundred years ago. But, unsatisfied with how they are usually done, he began to research and experiment, and wound up making his own needles, knitting sheaths, and trying to reconstruct commercial knitting techniques from before the industrial revolution.
He has some radical ideas, like they could make 48 ganseys a year back then, while it hurts your wrists to make one in two months nowadays, because they used different techniques and different tools. And he's working on proving his theories practical. I went back and read his blog from 2006 to the present, and it's a fascinating odyssey. Check it out. I'd love to hear some feedback.
