Hi, I think I might have missed this when you first posted... I started selling vintage clothing with trying out a bit here and there, Ebay, which I find in the end just too much work for listing IMHO, a local auction site here in Switzerland - easy and cheap to list, but just not the right audience, and then decided to use my Etsy shop which I had originally started for my collage art. No, my sales didn't hit the roof straight away, but after a few first sales, I felt encouraged and have gone on since then. I also sell vintage accessories, some bits and bobs from my personal collection, a bit of vintage kitsch - but have decided now to focus more on vintage sewing patterns and what goes with it. I find some good stuff here, and it's easy to send. Swiss Post just raised their rates for bigger parcels a year after I started with vintage in my Etsy shop, so that makes it a bit harder to sell bigger things. But the letter rates still seem to be quite competitive, as I sell my patterns all over the world. What I have found is that it takes patience, yes, you've got to work it, build a bit of a following I guess and give it some time to grow. My best friend has two Etsy shops where she sells vintage jewelry (one for the "kitsch" and novelty stuff, one for the more "serious" things that might interest collectors) and she's been learning a lot too. She says that being on Pinterest helped her a lot - following people with interesting boards that had a good following that might tie in with her stuff, and also doing her own boards. I've just started to dip my toes into Pinterest, but it's fun and I can see on my Etsy stats that it generates traffic. I've certainly started getting more likes on Etsy since I've been doing more, more of my things being used in treasuries etc., and sales are going steady. There are so many ways now that you can connect your shop with other social media etc. - like Facebook pages and shop apps to link an Etsy shop through there, or apps that let your shop appear on the side bar of a blog (I'm sure these things exist for Ebay too!).
What we have learned too is that you can never tell what sells and what not. We've both sold things that we listed without a lot of hopes of selling, and other we think are great but they're just not moving. Who knows... For me, Etsy at this point is great, because it's easy to use, I'm ok with the fees, it's a nice community and I can reach the whole world. An added bonus for me is that I can list in more than one language. I list in German and English, and when I sell something I can see in which language the buyer viewed the page when making the purchase. I don't think I'd be selling so much to Germany if I didn't do that.
