So everyone knows that high-born ladies were big into embroidery. There are several ladies with public talents for embroidery, and Amelia, for one, would love a handy stitch and bitch, for creativity and gossip, among other things.
That said, knitting is also period appropriate! While usually more common in lower classes, anyone needing warm things for cold climes could be in need, and what better way to show support to the troops than making sure they are prepared?Crochet doesn't seem to make its way into ladies magazines until the 1840s, though. Pout. Still, plenty of opportunities to use fiber arts for in character bonding!
