"I was begun to knit a pair of black and white stockings to Marion to let her see some of our Sanquhar patterns." (letter dated 20 September 1869)
Anyway, it's good to see Sanquhar knitters in the news. Thanks to Melissa for this link. A' the Airts wasn't quite open yet when we visited Sanquhar in 2010, just "coming soon" in the windows; glad to see it's going strong now.
