OH available so got him to vid the fingers while I tried to spin the assisted twist.
A bit better than the youtube one I made when that I tried to video myself.
The ratio is 12:1 over 1/2 inch - so 24 twists per ince.
This single turned out at 36 wraps per inch. It's pretty robust but still fairly soft. If it works out well as a 2-plied lace yarn (for knitting) I might prefere it to the other ways I;ve tried for that type of yarn.
Snow all melted away Sunday night with the rain. Now all is mostly green again and the sheep are lying about ruminating.
