Well spotted, Wladimir. It's also interesting when you compare some of the 'spinning' ladies' hair. It's like they are spinning their own hair (remember that a spindle is used to twist loose fibres into threads). Note that in both the middle and right nymph, their hair is explicitly connected to the spindle.
I'd certainly like to see what's under that fold, and if it's a spindle, which type.
