How is surface pattern different from a seamless pattern file?+
Seamless describes how the tile is built; surface pattern describes what it is for. Surface work is judged on how it looks once applied to a product, which is a question about scale rather than about the tile.
Why offer the same design at several scales?+
Because the application decides it. The same floral can be a large-scale wallpaper or a ditsy cotton print, and selling both widens who the file suits without any new artwork.
What license terms should the listing state?+
State plainly whether the buyer may use it on products for sale, and whether there is any limit. Vague terms are the single biggest source of disputes in this category.
Do I need to know print-on-demand specifics?+
Enough to give dimensions. Buyers uploading to a fabric or wallpaper service need the tile size in inches or centimeters, not only in pixels.
Can I sell surface pattern designs made with AI on Etsy?+
Yes, with disclosure. Etsy allows AI-assisted designs under its Creativity Standards as long as you are clear about how they were made.
