Not in any way directly related to eBay, but I bet I can get some good replies here anyway.
On Facebook, there is someone who wants to buy uncut, FF sewing patterns, doesn't care what kind, so evidently wants for reselling somewhere. Also on FB there are quite a few posters selling brand new patterns, so have to ask, is this a thing now? Just gave away a bunch to a local thrift, but have to confess that very few of them were uncut.
