I have taken up my barely-used supported Russian spindle again. It's working quite nicely now with combed merino (from Alberta) instead of Shetland. The merino fibres draft more easily; Shetland fibres grip each other.
I brought it along to the knit and natter. It was cool. A man and a woman were in the sandwich shop. They noticed me spinning and tried to get a better look without drawing attention. I think they might have been from India or somewhere in Asia where people spin with supported spindles.
