Stop: Dummy time :)
"english"? You mean like spin you put on a pool ball?
What I'm reading sounds like this:
push thumb from heel to tip in short strokes (not one long heel-tip ride) and make like a spiral motion with the thumb say from left bottom of stroke to right top of stroke.
I can't draw it here but I'm thinking of the stripe on a barber pole or the spiral on a drill bit. Lower left to upper right.
Am I anywhere near the ballpark? What sensation should I be looking for, I'm thinking a grabbing sensation as if the edge sticks into the skin just enough to stop the spiral from happening.
