My wife crochets and cans (jams, jellies, pickles). My sister crochets, knits and keeps bees. My mom quilts. So I don't really have a sense that these abilities are dying, don't you worry.
I even(!) have a male friend who crochets quite well, since there's no reason a guy can't learn to do this stuff either. I'd like to be able to garden, if I ever have a space to garden in, and I can bake a pretty good loaf of bread (something one of my grandma's has never done by her own admission, actually).
