Speaking of points, there are an awful lot of pointy features on this glass wheel. If I had that hanging around my house for very long, I'm sure someone (probably me) would lose an eye. But I guess they didn't make a glass wheel because it was practical.
I'm also intrigued by the spinning technique. I think this is spinning from the fold. I'm amazed that the spinner (spinster?) seems to be getting such even yarn with what looks like no drafting.
Maybe the fiber turns back into Rapunzel's hair at midnight? But only if Rumplestilsken prevents her from pricking her finger on a pointy thing. (Or something like that.)
