Alabaster? Candle holder leaves thingy.

I've been to a few US flea markets, albeit they were in LA, so possibly on the fancy end. Pasadena.

Yes, you pay for a space, can be as cheap as a fiver or if you've a van, about twenty. There are burger vans, which are an essential part of the experience, and these days, often a good espresso van too. SOmetimes a bouncy castle. Mostly it's private tat and house clearance blokes, some car boots get meat stalls, fruit & veg and other new goods. There's a woman at one I go to who sells really good designer end of range and sample clothes for absolute peanuts. Depends on the local council's licence policy. I hate the crack of dawn ones, I frequent those which kick off about nine ish.
