We value the copyright of all images and the work of all artists. Artists on Spoonflower own the rights to their original artwork shared on our site. Find more information about copyright in our Terms of Service.
We don't have any language in our terms of service that specifically addresses selling goods made with Spoonflower products. If you are considering a design for commercial use, we'd encourage you to contact individual designers directly. If contact information is available on a designer's shop page, you can reach out to them directly to inquire.
We have found that most designers are very happy to be asked and would just like to be credited for their designs if possible, but it certainly never hurts to be sure when it comes to selling items to others.
