I do hand embroidery and find it quite enjoyable.
This isn't really and art or craft (I think?), but I recently went to the Vandalia Festival here in Charleston, WV. It's a really fun festival with lots of bluegrass music, TONS of pretty quilts, food, etc. Well, I joined in a square dancing thing (which I've never done before in my life - it was SO fun!) and later as I was watching the people dance, I thought it was sad that they were mostly only older people. There were very few people my age (20s). And I just sat there hoping and praying that the traditions would never die out.
