It's a wonderful skill to have. My grandmother used to do all those types of things--crocheting, knitting, etc. She made beautiful items and gave them to all her children and grandchildren. I still have fond memories of her sitting in front of the TV, and knitting or crocheting.
(When I was about 10 years old, she tried to teach me knitting, and I didn't have the patience for it and wanted to scream!
I kept knitting and then pulling out all my mistakes--finally decided this was for the birds.
) I wouldn't be adverse to trying it again, though, as an adult, but I don't know anyone now who does either knitting or crocheting.
