Spinning with a French Spindle

Hi guys! Here's another demo video with a vintage French Spindle. This is also a test video using my iPhone, as I wanted to see how well it worked. Feel free to let me know in the comments how this compares to the regular camera used in other videos.
The French Spindle differs from the Bulgarian spindles primarily at the top tip, where there's a corkscrew instead of a knob. Some, like the one I own, has that carved in while others have a metal attachment with the corkscrew or hook. This french spindle is an absolute workhorse, spinning all sorts of thicknesses, packing on a lot of yarn until it becomes uncomfortable, and is even used for plying by quickly rolling it in the palm (demo video for that to come later).
