@ossobuco,
Off on my own riff re a guy who knew silk -
He also collected Stickly furniture; his girlfriend, a great pal of mine who I still care about as friend, but we haven't emailed in a while - first met from school in our medium age - we all got along, back then.
Besides the esoteric stuff, he was or still is quite a photographer, used to roam downtown LA in the wee hours and dark alleys and photo, his stuff on several album covers. I have one of his prints.
I hesitate to look him up - we are all so old now.
