If you read my post here on the top 20 vintage sellers on Etsy, you'll find that most of the top vintage sellers have some things in common. Most of the items that are selling are smaller items like jewelry, ephemera, and bits and bobs. Of course that is not all, but it surprised me to learn that while larger decor items are big sellers in Occasional sales that I've been to, I didn't find one Etsy store in the top 20 whose main inventory was these items! Hmmmm.
The top seller list was based on number of items sold, not amount of money made. Since smaller items would cost less, that may be why they sell more of these items. Also the shipping costs may figure into that in that it costs more to ship a larger item than a smaller one so people might prefer to purchase these items in person. Of course, if they listed the top 20 shops that make the most money, maybe the list would include sellers of larger items. I'd like to see that list!
I also think that staging larger items in vignettes makes a big difference. So why not take photos of vignettes with your items for sale to enhance their look online? I think it is Country Living magazine that shows photos of decorated rooms and then breaks it down into individual pieces, listing where you can purchase them. I wonder if something like that could be done in my Etsy shop?
I've only done a little research into this but will continue to do more. So far it appears that:
1) Smaller items sell more often in Etsy shops than larger items
2) Jewelry and Ephemera are popular sellers
Since I'm just setting up my Etsy shop I'm going to keep this in mind. I'll still list larger items and see how they do, however. I also have found that there is something for everybody and eventually even the larger pieces will sell, though maybe not quite as quickly.
