Etsy is a wonderful place to shop for new handmade items. It's also a great place to shop for vintage goodies. I love looking for both handmade and vintage items there!
Etsy recently made some changes, however, that make it a little harder to find vintage unless you know what you are doing.
As of May 5th, the default search on Etsy is only for handmade items. If you want to look for vintage items, you have to change your search (in the drop down menu at the top) to "vintage: tags and titles". You can also search for "all items: tags and titles" if you want to see all items, handmade and vintage, at once.
