Wool. . . the only natural fiber that even when soaking wet will still retains body heat!!
Until I knew this I always ‘gripped’ about the fools that made wool (socks/glove liners/sweaters) part of our lucky bag.
Seems I was the uninformed fool!
I learned knitting in school in Germany, but I always had trouble with the heel, and needed help with that. I knitted a beautiful sweater for myself after I got married and still wear it.
