One idea that might get some interest is Collecting Stuff. Any stuff, really, from cameras to LPs. Not just out of general interest as to who collects what. Also useful for avoiding snags. In recent set of posts on Sunflower thread, another member was told that a batch of vinyl LPs she’d inherited were “worth nothing”. Opinion from potential buyer who hadn’t even seen them and who was no doubt quite keen to get hands on some “worthless” 60s Elvis and the like. OK, they might only be worth a few pounds but some might fetch upwards of £500.
Was also going to suggest something about, say, music but what with beauty being in the ear of the listener, I reckon widely varying tastes in styles would make it difficult to hold together.
