I'm eager to read all the replies.
I've gone to Etsy many times, love looking at the items available but have never purchased.
Recently I've been thinking of selling my fabric postcard creations on Etsy, there are alot there for sale. Which might be the problem.
Rarely do I find them available on eBay, but when I do they are incredibly high priced compared to Etsy. Altho admittedly some on Etsy are high priced and DO sell.
So maybe it is a matter of getting started on Etsy and staying long enough to garner a following.
