Do you use flea markets as a way to suppliment your income?

What we found goes quite quickly, is if you have a pile of magazines. People always go for that. Or pay attention to what people ask for. I work at a craft market at the moment (not quite the same as a fleamarket, I know) and then someone asked for dreamcatchers. We did have one, but it was expensive, unwieldy and about 2 meters long, obviously not too mobile, so I said, offhand to the manager of the stall, why don't I make us some smaller ones? She said, yeah, why don't you? I made two (that was about three weeks ago) and one sold last weekend. So it looks as if I should start making some more...
