What would be the most successful way of selling own paintings and crafts (online)?

Start you own website. Dont use Etsy, or Ebay or Any Other. �200.00 pounds can start you a great ecommerce website. I could write all day telling you the problems you may face selling with these companies, but I wont. Put all your effort and time in it. It will pay off. There is a high demand for custom wedding card invitations at the moment. Make them as cheap as you can with the highest of quality and you will not have to spend a penny on advertisment. When you start, drop me a line, my contact details are here ( a href="http://www.londonprintshop.com" rel="nofollow"http://www.londonprintshop.com/a ),we are still looking for a good wedding card printer to contract our wedding cards printing to.
