Where should I sell my designs?

You have two main options - your own website, or a marketplace. We recommend Etsy and Shopify. Etsy is a cool digital marketplace, which has an emphasis on custom / handcrafted stuff. Simply sign up, set up a shop, and you are ready to go without creating a website. On the other hand, Shopify gives you the freedom to create whatever online shop / website you want. Contact a personal manager, they'll go into more details. We also have a blog post planned about this topic.
