Artists who want to sell art online can sign up on websites like Redbubble and Zazzle, described above. These sites are free and simple to use and only require the artists to upload their designs. Everything else, from customer service to shipping and returns, is handled by the company. If you decide you want to be in control of all aspects of your products, you can also sell your art on Amazon, Etsy, or even create your own e-commerce website.
