I have tried to set up my Folksy but I had some issues verifying that it was me at the final stages before setting up shop. I have set up paypal but as I couldn't get onto making the shop on Folksy, I have put my work on BigCartel. Unlike Folksy, who charge for each item you put in your shop, BigCartel do not charge when you use the basic package. The basic package includes 5 items, 1 photo per item, url.
Etsy seems to be a popular online shop used by a lot of people I have been looking at. They also charge per item you put in your shop.
