I discovered etsy in 2008 and let's just say I spent a LOT of time (and money!) there those first few years. I'm rarely on etsy now, but only because I don't buy these kinds of things much anymore ... but I envy you that you are just discovering it. It's such a cool place, although a total time suck: be warned.
What I like most about etsy is the chance to purchase from all over the world, and the chance to deal directly with artists / vendors. I always use PayPal and have never had a problem.
Like Deb and Fern, I have original art from etsy: a tiny oil painting of a sailboat, from Italy, that I gave to my husband; a beautiful painting of a house in a field of Tulips, from Poland; a strange and lovely sculpture; a print of a woman wearing a dress made of flowers (and lots of other prints).

Etsy is also great for Christmas ornaments if you celebrate the holiday. I bought a box of 24 vintage glass ornaments from a collector, as well as new handmade ornaments.
Jewelry -- hammered silver and gold narrow bands, a set of seven, that I wear every day. My favorite stud earrings, which are from Israel, and my favorite hanging earrings too. Numerous items for my daughters.
Posters -- vintage Elvis Costello concert poster for our music room. New York subway poster.
Knitted items (for those who don't knit). There are a ton of knitters who sell on etsy -- everything from mittens to purses.
I've also purchased iphone cases, a handmade leather ipad case, personalized water bottle wrappers for my daughter's graduation party, natural pomegranate ginger blueberry lollipops, dog tags and collars, clothing .... the list goes on and on.
Happy exploring!!!
