And what is going on with the yarn coming down from above? My best theory is that she's spinning/plying flax in a fashion similar to the Egyptian method illustrated here:
I have read that sometimes the yarns would be run over an overhead hook to provide more length and drying time for the yarn. What do you think?
BTW, did you notice the spindles?
11/23 - Edited to add: Commenter Manise has an excellent theory: "The right fuller cop looks plied. I think she wound 2 plies side by side by hand onto the left spindle kind of like a noste and then plied it onto the right one."
I think she has something, there. And the spinner may simply be biting off the strands from the supply spindle. Make sense?
Many thanks to my friend Dianna in Saskatchewan for bringing the LIFE photo archive to my attention.
