Hi There, I haven’t done a video on cloth advancement but I can offer a few suggestions. There is a round nut at the end of the screw that can be adjusted to increase or decrease the tension on the cable. She might like to loosen than off a tad. Sometimes grit and dust build up on the wooden disc that the cable wraps around which can cause it to stick. She could take the cable off and clean that disc. Once it is nice and clean she could take the end of a candle and rub it on the disc and the wax will act as a lubricant. After that wrapping the cable around the disc again, making sure there are no overlaps. That should make it smooth as a babies bottom :). Hope this helps.
