I have thought about starting up an etsy shop for my jewelry, but from talking to others it sounds like sales are very slow and they do better selling locally, like through consignment or word of mouth. So many people make craft items that it is tough. But given that etsy isn't exactly an expensive way to advertise your stuff, I may very well do it anyway.
I've had an etsy shop for over a year and sales are *very* slow. I do a little better selling supplies than handmade craft items, but still find it to be a tough venue for selling. It's fine if you just want to liquidate some stuff and don't care how long it takes, but if you are making items with the intention of selling I'd look for other avenues first (although it is not a bad idea to keep an etsy shop and stock with whatever didn't sell at your shows, etc.) If you think you may start an etsy shop, feel free to PM me and I'll give you a few tips I've picked up along the way.
FWIW, I have a friend who made jewelry for a while and did very well selling at home parties.
