Spinning fiber into string is very worthwhile.
It is tangentially related to loom weights (the problem of fiber is: how not to tangle. It wants to tangle.) but doing it oneself answers a bunch of other important questions.
And it takes hair, from a sheep (for example), in one hand, and skill and a weighted stick in the other, and in between them is the magic of humanity.
Yes, it makes me cry every time. Indistinguishable from magic.
