Etsy serves a handful of demographics—mostly people with more yarn than sense, and collectors of homespun whimsy (and those who would date either). More and more, though, Etsy is catering to those who prefer deadstock to homemade. Like many in the Etsy community, I long ago charted a steady course to an eventual appearance on Hoarding: Buried Alive; mine was first mapped when I ransacked Philadelphia thrift stores for western shirts and corny charity tees in the 90s. Thanks to well-stocked and well-priced shops like County Line General and Wooden Sleepers, that call from TLC might come any day.
I've been compiling a weekly (or so) roundup of the best items listed on Etsy vintage, with a continuous lean toward made in US and UK goods of wool, cotton, and silk, and some fine forgotten brands. Check it out.
