And in honor of the American holiday, I leave you with this knitting-related bit of history:
In Philadelphia, “Mom” Rinker was a tavern keeper whose work put her in the company of British soldiers. She was also a spy. Rinker often spent her days in a town park where she sat up on a high rock, knitting copious numbers of garments. As she knit, she concealed messages in balls of yarn and then dropped them to American couriers below.
