Want to know where your genuine Shetland yarn comes from? Or perhaps, used to come from... check out In Sheep's Clothing, a rare vintage silent film of shepherds on Shetland herding and "rooing" sheep, then turning the wool into hand-knitted garments. The traditional Shetland sheep shed its wool, so had to be "rooed," or hand-plucked. The film dates from 1932, and is in the Scottish Screen Archive. Click on the picture to take you to the site.
I just love this image of a woman hugging and comforting an antsy sheep.
