Knitting during war time was definitely a THING in WWI and WWII. Not only was it incredibly useful, but it lent a sense of purpose and community to those on the home front, as well as physical and emotional support to those fighting.
While the most urgent need was for socks, there was a option for everyone: "Beginning knitters would make mufflers. School kids would knit simple nine-inch squares that would be sewn together into blankets. Those who never mastered purling could make bandages: 15-20’ lengths knit in garter stitch with 100% cotton yarn." SOURCE
Do you currently knit for those in the armed forces? Or perhaps you did in WWII. I would love to hear about your experience and how you give back.
