Worsted than what?
There was some extremely abrasive stuff in the eighties that showed no sign of a weave. I wondered sometimes if it might be some kind of felt. Somebody pulled some tables out of storage that had been there thirty years or close to it, barboxes.
They had that crap on them and despite working with my hands and having pretty decently tough working hands this stuff had cut the fingerprints off of all of the places I bridged. It was abrasive when new, as bad or worse thirty years later. I played about an hour or two. I think I would have been leaving blood spots on the table if I had played another hour.
